dg2_ddi_pre_enable_dp() has outlived its usefulness so eliminate
it.
The one thing that tgl_ddi_pre_enable_dp() is missing that we
need is intel_ddi_config_transcoder_dp2(). So we'll bring that
over.
tgl_ddi_pre_enable_dp() does also have a few things that
dg2_ddi_pre_enable_dp() didn't have:
- icl_program_mg_dp_mode() -> nop due to intel_phy_is_tc()==false on DG2
- intel_ddi_power_up_lanes() -> nop due to intel_phy_is_combo()==false on DG2
- intel_ddi_mso_configure() -> only matters for MSO panels
Another slight difference is that dg2_ddi_pre_enable_dp() was
missing a bigjoiner check around intel_dsc_enable(), which
tgl_ddi_pre_enable_dp() does have.

Currently we just use all the hdmi_deep_color_possible() stuff
to compute whether deep color is possible, and leave the 8bpc
case to do its own thing. That doesn't mesh super well with 4:2:0
handling because we might end up going for 8bpc RGB without
considering that it's essentially illegal and we could instead
go for a legal 4:2:0 config.
So let's run through all the clock checks even for 8bpc first.
If we've fully exhausted all options only then do we re-run
the computation for 8bpc while ignoring the downstream TMDS
clock limits. This will guarantee that if there's a config
that respects all limits we will find it, and if there is not
we still allow the user to override the mode manually.

The link service irq vector in DPCD 0x2005 contains the link status
changed bit to indicate the status should be checked. Only read and
check the link status when requested by the sink.
This also reduces the confusion around the buffer size for the combined
ESI and link status. Alas, we still need to take into account that all
link status helpers expect a buffer of DP_LINK_STATUS_SIZE (6) while the
link status in ESI only has 4 bytes.

Lots of machines these days seem to have a crappy type1 DP dual
mode adaptor chip slapped onto the motherboard. Based on the
DP dual mode spec we currently limit those to 165MHz max TMDS
clock.
Windows OTOH ignores DP dual mode adaptors when the VBT
indicates that the port is not actually DP++, so we can
perhaps assume that the vendors did intend that the 165MHz
clock limit doesn't apply here. Though it would be much
nicer if they actually declared an explicit limit through
VBT, but that doesn't seem to be happening either.
So in order to match Windows behaviour let's ignore the
DP dual mode adaptor's TMDS clock limit for ports that
don't look like DP++ in VBT.
Unfortunately many older VBTs misdelcare their DP++ ports
as just HDMI (eg. ILK Dell Latitude E5410) or DP (eg. SNB
Lenovo ThinkPad X220). So we can't really do this universally
without risking black screens. I suppose a sensible cutoff
is HSW+ since that's when 4k became a thing and one might
assume that the machines have been tested to work with higher
TMDS clock rates.

Replace the DEVICE_TYPE_DP_DUAL_MODE_BITS stuff with just
a DP+HDMI check. The rest of the bits shouldn't really
matter anyway.
The slight change in behaviour here is that now we do look at
the DEVICE_TYPE_NOT_HDMI_OUTPUT bit (via
intel_bios_encoder_supports_hdmi()) when we previously ignored it.
The one platform we know that has problems with that bit is VLV.
But IIRC the problem was always that buggy VBTs basically never
set that bit. So that should be OK since all it would do is make
all DVI ports look like HDMI ports instead. Also can't imagine
there are many VLV machines with actual DVI ports in existence.
We still keep the rest of the dvo_port/aux_ch checks as we
can't trust that DP+HDMI device type equals DP++ due to
buggy VBTs.

Now that we parse the DDI port info from the VBT on all g4x+ platforms
we can throw out all the old codepaths in intel_bios_is_port_present(),
intel_bios_is_port_edp() and intel_bios_is_port_dp_dual_mode(). None
of these should be called on pre-g4x platforms.
For good measure throw in a WARN into intel_bios_is_port_present()
should someone get the urge to call it on older platforms. The
other two functions are specific to HDMI and DP so should not need
any protection as those encoder types don't even exist on older
platforms.

Extend the vbt.ports[] stuff for all g4x+ platforms. We do need
to drop the version check as some elk/ctg machines may have VBTs
older than that. The oldest I know is an elk with version 142.
But the child device stuff has had the correct size since at
least version 125 (observed on my sdg), so from that angle this
should be totally safe.
This does couple of things:
- Start using the aux_ch/ddc_pin from VBT instead of just the
hardcoded defaults. Hopefully there are no VBTs with entirely
bogus information here.
- Start using i915->vbt.ports[] for intel_bios_is_port_dp_dual_mode().
Should be fine as the logic doesn't actually change.
- Start using i915->vbt.ports[] for intel_bios_is_port_edp().
The old codepath only looks at the DP DVO ports, the new codepath
looks at both DP and HDMI DVO ports. In principle that should not
matter. We also stop looking at some of the other device type bits
(eg. LVDS,MIPI,ANALOG,etc.). Hopefully no VBT is broken enough that
it sets up totally conflicting device type bits (eg. LVDS+eDP at the
same time). We also lose the "g4x->no eDP ever" hardcoding (shouldn't
be hard to re-introduce that into eg. sanitize_device_type() if needed).
Lightly smoke tested on a set of machines (one of ctg,ilk,snb,ivb each)
with both DP and HDMI (DP++). Everything still worked as it should.

CHV is currently straddling the divide by using parse_ddi_ports() stuff
for aux_ch/ddc_pin but going through all old codepaths for the rest
(intel_bios_is_port_present(), intel_bios_is_port_edp(),
intel_bios_is_port_dp_dual_mode()). Let's switch over full and use
i915->vbt.ports[] for the rest of the stuff.
dvo_port_to_port() doesn't know about DSI so we won't get into
any kind of "is port B HDMI or DSI or both?" conundrum, which
could otherwise happen on VLV/CHV due to DSI ports living in a
separate world from the other digital ports.
Including Jani's detailed analysis here for posterity:
"We stop checking for port A for CHV in intel_bios_is_port_present(), but
it's a warn and I don't recall any bug reports, so probably fine. We
could add a check in parse_ddi_port(), but meh.
Ditto for intel_bios_is_port_dp_dual_mode(), except it doesn't have a
warn.
The eDP check in intel_bios_is_port_edp() becomes slightly more
relaxed. Both the old and new check require these to be set:
- DEVICE_TYPE_DISPLAYPORT_OUTPUT
- DEVICE_TYPE_INTERNAL_CONNECTOR.
The old code also required these to be unset:
- DEVICE_TYPE_MIPI_OUTPUT
- DEVICE_TYPE_COMPOSITE_OUTPUT
- DEVICE_TYPE_DUAL_CHANNEL
- DEVICE_TYPE_LVDS_SIGNALING
- DEVICE_TYPE_TMDS_DVI_SIGNALING
- DEVICE_TYPE_VIDEO_SIGNALING
- DEVICE_TYPE_ANALOG_OUTPUT
It's possible we've added these just as a sanity check for broken VBTs
more than anything. I guess I'd see if actual problems arise.
Bottom line, I think the functional changes matter only for VBTs with
bogus data."
I agree that it should work assuming the VBT isn't totally insane.
Modern windows drivers also don't seem to check any of those
additional device type bits, which may or may not matter for older
devices (no idea what some old driver versions are checking).

Also the masks we're using now don't even match the actual hardware

The last user of intel_dp_pack_aux() outside intel_dp_aux.c got removed
in commit ad26451a7902 ("drm/i915/display: Drop PSR support from HSW and
BDW"). Make the function static again.
Rename the pack/unpack functions to follow the usual naming conventions
while at it.

All MG/DKL PHY register regions are evenly spaced offset-wise (0x168000,
0x169000, 0x16A000, 0x16B000) so the _MMIO_PORT() macro we use to access
their registers only needs the first two offsets. We can drop the
_PORT3 and _PORT4 offsets which are never directly referenced.

platforms; let's keep them separate from the general register pool.
