Fix potential null-pointer dereference at probe by making sure that the

The whiteheat driver assumes there are at least five pairs of bulk
endpoints, of which the final pair is used for the "command port". An
attempt to bind to an interface with fewer bulk endpoints would
currently lead to an oops.

Ignore DEVICE_TYPE_NOT_HDMI_OUTPUT and DEVICE_TYPE_DIGITAL_OUTPUT when
trying to determine the presence of eDP based on the VBT child device
type. Apparently a significant portion of VLV systems have these bits
set incorrectly, and so we currently fail to detect eDP on said systems.
This is based on an earlier patch [1] from Andreas Lampersperger.
Instead of ignoring the bits just on VLV as was done in the orignal
patch, we now ignore them for all platforms. We should still have
enough bits in there to avoid false positives (unless the VBT is totally
bonkers).
Quoting the orignal patch:
> When the i915.ko identify an eDP output on a valleyview
> board, it should be more slackly. The reason for that is,
> that BIOS DATA TABLES generated with intel BMP (Binary
> Modification Program) do not set bits for NOT_HDMI or
> DIGITAL_OUTPUT on the device type. Due to Adolfo
> Sanchez from Intel EMGD, this is not possible.
> To solve this problem and enable i915.ko on embedded
> vlv boards with eDP, we ignore this two bits.

An HPD interrupt may fire while we are in a function that changes
the PORT_HOTPLUG_EN register - especially when an HPD interrupt
storm occurs.
Since the interrupt handler changes the enabled HPD lines when it
detects such a storm the read-modify-write cycles may interfere.
To avoid this, shiled the rmw cycles with IRQ save spinlocks.
Changes since v1:
- Implement a function which takes care of accessing PORT_HOTPLUG_EN.

The VBT MIPI Sequence Block version 3 has forward incompatible changes:
First, the block size in the header has been specified reserved, and the
actual size is a separate 32-bit value within the block. The current
find_section() function to will only look at the size in the block
header, and, depending on what's in that now reserved size field,
continue looking for other sections in the wrong place.
Fix this by taking the new block size field into account. This will
ensure that the lookups for other sections will work properly, as long
as the new 32-bit size does not go beyond the opregion VBT mailbox size.
Second, the contents of the block have been completely
changed. Gracefully refuse parsing the yet unknown data version.

It would be initialized just moments later by i915_init_vm.
Rearrange the code such that i915_init_vm() is next to its callers
inside i915_gem_gtt (and so we can make it static). After removing the
dance around the files, it is clear that we are repeating some work
inside the initializers (such as calling drm_mm_init() multiple times),
so take advantage of the refactor to also remove some redundant code and
clean up the interface.
v2: Commit msg update,
s/i915_init_vm/i915_address_space_init, move to i915_gem_gtt.c,
init address_space during i915_gem_setup_global_gtt for ggtt.
v3: Do not init global_link - we are adding it to vm_list moments later,
make i915_address_space_init static, use OOP style parameter order.

Finally managed to dig up enough hints as to where the stolen
reserved stuff lives on ctg/elk. So add the code to decode it.
This was a combination of old chipset specs, diggin up an old
elk grits release with an ctg/elk AubLoad etc.
This was only tested on an elk as I don't have a ctg here
unfortunately.
This leaves ilk as the only platform that doesn't have a way
to detect this stuff. Looking at the register contents on my
ilk, it might be that the elk way works there too, but I
can't be sure since I can't affect the amount of reserved
memory on that machine, and if I am to trust the register
contents, by default it would reserve 0 bytes.

I only tested this on BDW and SKL, but since the register description
is the same ever since gen4, let's assume that all gens take the same
register format. If that's not true, then hopefully someone will
bisect a bug to this patch and we'll fix it.
Notice that the wrong fence offset register just means that the
hardware tracking will be wrong.
Testcases:
- igt/kms_frontbuffer_tracking/fbc-1p-primscrn-pri-shrfb-draw-mmap-gtt
- igt/kms_frontbuffer_tracking/fbc-2p-primscrn-pri-shrfb-draw-mmap-gtt
v2:
- Add intel_crtc->adjusted_{x,y} so this code can work independently
of intel_gen4_compute_page_offset(). (Ville).
- This version also works on SKL.

The spec says the register should have that value for the entire time
that FBC is enabled, so apply the WA before we enable FBC.
Notice that we also have this WA for ILK/SNB, but it is implemented at
init_clock_gating(). I could move the IVB/HSW/BDW WA code to
init_clock_gating() too, but since we recently had some complaints
about WAs not staying after being set, I'm going to play safe and keep
this here for now.

The FBC hardware for these platforms doesn't have access to the
bios_reserved range, so it always assumes the maximum (8mb) is used.
So avoid this range while allocating.
This solves a bunch of FIFO underruns that happen if you end up
putting the CFB in that memory range. On my machine, with 32mb of
stolen, I need a 2560x1440 mode for that.
