[00/42] Enable Lunar Lake display

Message

Cross posting this to the i915 and xe mailing lists. The basic platform
enabling for Lunar Lake is already applied in xe[1]. This patch series
adds the display support, that will be driven by i915.

A few notes from the series:

	1. This is based on drm-xe-next branch since this is where it
	   can be tested. It should be good enough for reviewing and
	   getting early feedback, but not for applying. drm-xe-next
	   will soon be on a more recent drm-tip, that will make it
	   easier to get some of the patches landing. All the patches
	   prefixed with drm/i915 are expected to eventually be applied
	   through the drm-intel branch.
	2. The first 6 commits can be ignored: they are things already
	   applied in drm-intel. With the IP/platform separation, there
	   was a lot of prep work besides those patches, that already
	   landed there so we minimize the patches for new platforms.
	3. Patches 7 through 10 can also be ignored: they are not
	   applied yet, but being reviewed in other patch series by its
	   author[2].
	4. Patch 11 allows xe to build when the patches the follow are
	   applied. Depending on the timeline how things end up landing,
	   this patch may need to be squashed in the "Initial Xe display
	   support"
	5. Last patch finally enable the display support in xe once all
	   the patches on the i915 side are applied.

I also ask for the original authors of the patches to double check their
own patches as there were some adjustements needed in order to rebase,
cleanup and fix some of the patches.

Lastly as things get reviewed I may want to split up this series in
smaller pieces and do some re-ordering to expedite the i915
