drm_helper_mode_fill_fb_struct()
Plumb the format info from .fb_create() all the way to
drm_helper_mode_fill_fb_struct() to avoid the redundant
lookup.
For the fbdev case a manual drm_get_format_info() lookup
is needed.

Make xe->display pointer opaque to most of core xe driver. A few places
now need explicit include of intel_display_core.h.
With this dependency broken, changes in display should cause radically
less recompilation of xe.

intel_display
Going forward, struct intel_display is the main display device data
pointer. Convert intel_fbdev.[ch] and as much as possible of
intel_fbdev_fb.[ch] to struct intel_display.

Some users apply PINNED and some don't when using pin_map(). The pin in
pin_map() should imply PINNED so just unconditionally apply it and clean
up all users.

FBDEV ggtt is not restored correctly, add missing GGTT flag to
intel_fbdev_fb_alloc to make it work. This ensures that the global
GGTT mapping is always restored on resume. The GGTT mapping would
otherwise be created in intel_fb_pin_to_ggtt() by intel_fbdev anyway.
This fixes the fbdev device not working after resume.

As per recommendation in the workarounds:
WA_22019338487
There is an issue with accessing Stolen memory pages due a
hardware limitation. Limit the usage of stolen memory for
fbdev for LNL+. Don't use BIOS FB from stolen on LNL+ and
assign the same from system memory.
v2: Corrected the WA Number, limited WA to LNL and
Adopted XE_WA framework as suggested by Lucas and Matt.
v3: Introduced the waxxx_display to implement display side
of WA changes on Lunarlake. Used xe_root_mmio_gt and
avoid the for loop (Suggested by Lucas)
v4: Fixed some nits (Luca)

The flags stored in the BO grew over time without following
much a naming pattern. First of all, get rid of the _BIT suffix that was
banned from everywhere else due to the guideline in
drivers/gpu/drm/i915/i915_reg.h that xe kind of follows:
Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.
Here the flags aren't for a register, but it's good practice to keep it
consistent.
Second divergence on names is the use or not of "CREATE". This is
because most of the flags are passed to xe_bo_create*() family of
functions, changing its behavior. However, since the flags are also
stored in the bo itself and checked elsewhere in the code, it seems
better to just omit the CREATE part.
With those 2 guidelines, all the flags are given the form
XE_BO_FLAG_<FLAG_NAME> with the following commands:
git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \
-e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \
-e 's/XE_BO_CREATE_/XE_BO_FLAG_/g'
git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \
-e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64K|GGTT_INVALIDATE)/XE_BO_FLAG_\1/g'
And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to
follow the coding style.

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there.
We do this by recompiling i915/display code twice.
Now that i915 has been adapted to support the Xe build, we can add
the xe/display support.
This initial work is a collaboration of many people and unfortunately
this squashed patch won't fully honor the proper credits.
But let's try to add a few from the squashed patches:
