79c520bc0f drm/i915/dp: Make has_gamut_metadata_dip() non static 
Make has_gamut_metadata_dip() non static so it can also be used to
at other places eg in intel_dp_aux_backlight. So that we can check
if HW is capable of sending SDP which helps us decide if we use
AUX based HDR control or via SDP.

56ac367dbf drm/i915: Polish types in fb calculations 
Be a bit more consistent in our use of integer types in
the fb related calculatiosn. u32 we generally only use
for ggtt offsets and such, and everything else can be regular
(unsigned) ints.

There's also an overabundance of consts for local variables
in skl_check_main_surface() which is not something we generally
do. So get rid of those while at it.

6907d4fa5e drm/xe: Nuke xe's copy of intel_fbdev_fb.h 
For some reason xe and i915 each have an identical (fortunately)
copy of intel_fbdev_fb.h. The xe copy actually only gets included
by xe's intel_fbdev_fb.c, and the i915 copy by everyone else,
include intel_fbdev.c which is the actual caller of the
functions declared in the header.

This means the xe and i915 headers are free to define/declare
completely incompatible things and the build would still succeed
as long as the symbol names match.

That is not a good thing, so let's nuke xe's copy of the header
so that everyone will use the same header, and be forced to
agree on the same API/ABI.

Define the contenst is VBT blocks 19,30,32 (Display Configuration
Removal Table) contents. There are three variants of this block:
pre-IVB, IVB, HSW+, with each having slightly different entries.

Curiously many HSW/BDW machines seem to have both the IVB and HSW+
variants in their VBTs simultanously. No idea why.

55c6b98676 drm/i915/bios: Define ALM only VBT block 9 contents 
For some reason ALM VBT has two dot clock override tables.
One as the normal block 15 and a second one as block 9.
The table in block 9 has no row_size/num_rows information.

On my Fujitsu Lifebook S6010 only the block 9 table has actual
data in it. Block 15 is present but all zeroes.

Define the contents of VBT block 15 (Dot Clock Override Table)

The contents were reverse engineered by intuition. The gen2 stuff
seems solid as I can verify that against real world VBT data. The
gen3 stuff less so as all the gen3+ VBTs I have just filla the
entire block with zeroes.

Define the contents of VBT block 10 (Mode Removal Table).

There seem to be two variants:
- 8 byte entries for desktop systems
- 10 byte entries for mobile systems, with the extra
  panel_flags being a bitmask of LFPs

It seems starting from HSW only the mobile variant is
used anymore.

Define the contents of VBT block 5 (Generic Mode Table).

Details were mostly gleaned from some VBIOS sources.

There are apparently two variants of the block: ALM only
vs. MGM, defined here as bdb_generic_mode_table_alm
and bdb_generic_mode_table_mgm. And those are the only two
platforms where I've seen this block.

Define the contents of VBT block 4 (Mode Support List).

Slightly crazy layout with a variable length list at the start,
followed by the length of said list.

No real idea what these "Intel mode numbers" really are. What
I see in real world VBTs seems to be always the same list of
26 numbers, ranging between 0x30 and 0x84.
