drm/xe/xelp: Expose AuxCCS frame buffer modifiers on Alderlake-P

drm/xe/xelp: Expose AuxCCS frame buffer modifiers on Alderlake-P

Now that we have implemented all the related missing bits we can enable
the AuxCCS compressed modifiers which were disabled in
cf48bddd31de ("drm/i915/display: Disable AuxCCS framebuffers if built for Xe").

Tested with KDE Wayland, on Lenovo Carbon X1 ADL-P:

        [PLANE:32:plane 1A]: type=PRI
                uapi: [FB:242] AR30 little-endian (0x30335241),0x100000000000008,2880x1800, visible=visible, src=28
                hw: [FB:242] AR30 little-endian (0x30335241),0x100000000000008,2880x1800, visible=yes, src=2880.000

Display is working fine - no artefacts, no DMAR/PIPE faults.

v2:
 * Adjust patch title. (Rodrigo)

v3:
 * Complete rewrite based on the display parent interface.
