Adds basic support for the new display classes available on GB20x GPUs.
Most of the changes here deal with HW method moves, with the only other
change of note being tweaks to skip allocation of CTXDMA objects, which
aren't required on Blackwell display.

Add drm_panic support for nv50+ cards.
It's enough to get the panic screen while running Gnome/Wayland with
an nv50+ nvidia GPU.
It doesn't support multi-plane or compressed format yet.
Tiling is tested on GTX1650 (Turing), GeForce GT 1030 (Pascal) and
Geforce 8800 GTS (Tesla).

Replaces a bunch of unnecessarily duplicated boilerplate in per-chipset
code with a simpler, common, implementation.
Channel "awaken" notify code is completely gone for now. KMS has never
made use of it so far, and event notify handling is about to be changed
in general anyway.

This change adds the dma_resv_usage enum and allows us to specify why a
dma_resv object is queried for its containing fences.
Additional to that a dma_resv_usage_rw() helper function is added to aid
retrieving the fences for a read or write userspace submission.
This is then deployed to the different query functions of the dma_resv
object and all of their users. When the write paratermer was previously
true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise.

The nouveau KMS driver will call drm_plane_create_zpos_property() with
an init value depending on the plane purpose.
Since the initial value wasn't carried over in the state, the driver had
to set it again in nv50_wndw_reset(). However, the helpers have been
adjusted to set it properly at reset, so this is not needed anymore.

When it comes to gamma or degamma luts, nouveau will actually skip the
calculation of certain LUTs depending on the head and plane states. For
instance, when the head is disabled we don't perform any error checking on
the gamma LUT, and likewise if no planes are present and enabled in our
atomic state we will skip error checking the degamma LUT. This is a bit of
a problem though, since the per-head gamma and degamma props in DRM can be
changed even while a head is disabled - a situation which can be triggered
by the igt testcase mentioned down below.
Originally I thought this was a bit silly and was tempted to just fix the
igt test to only set gamma/degamma with the head enabled. After a bit of
thinking though I realized we should fix this in nouveau. This is because
if a program decides to set an invalid LUT for a head before enabling the
head, such a property change would succeed while also making it impossible
to turn the head back on until the LUT is removed or corrected - something
that could be painful for a user to figure out.
So, fix this checking both degamma and gamma LUTs unconditionally during
atomic checks. We start by calling nv50_head_atomic_check_lut() regardless
of whether the head is active or not in nv50_head_atomic_check(). Then we
move the ilut error checking into nv50_head_atomic_check_lut() and add a
per-head hook for it, primarily because as a per-CRTC property DRM we want
the LUT to be error checked by the head any time it's included in an atomic
state. Of course though, actual programming of the degamma lut to hardware
is still handled in each plane's atomic check and commit.

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_check.
The conversion was done using the coccinelle script below plus some
manual changes for vmwgfx, built tested on all the drivers.

UEFI/RM no longer use IED scripts from the VBIOS, though they appear to
have been updated for use by the x86 VBIOS code, so we should be able to
continue using them for the moment.
Unfortunately, we require some hacks to do so, as the BeforeLinkTraining
IED script became a pointer to an array of scripts instead, without a
revbump of the relevant tables.
There's also some changes to SOR clock divider fiddling, which are
hopefully correct enough that things work as they should.
AFAIK, GA100 shouldn't have display, so it hasn't been added.

While most of the functionality on Nvidia GPUs doesn't require using an
explicit handle instead of the main VRAM handle + offset, there are a
couple of places that do require explicit handles, such as CRC
functionality. Since this means we're about to add another
nouveau-chosen handle, let's just go ahead and move any hard-coded
handles into a single header. This is just to keep things slightly
organized, and to make it a little bit easier if we need to add more
handles in the future.
This patch should contain no functional changes.

While certain modeset operations on gv100+ need us to temporarily
disable the LUT, we make the mistake of sometimes neglecting to
reprogram the LUT after such modesets. In particular, moving a head from
one encoder to another seems to trigger this quite often. GV100+ is very
picky about having a LUT in most scenarios, so this causes the display
engine to hang with the following error code:
disp: chid 1 stat 00005080 reason 5 [INVALID_STATE] mthd 0200 data
00000001 code 0000002d)
So, fix this by always re-programming the LUT if we're clearing it in a
state where the wndw is still visible, and has a XLUT handle programmed.
