These patches modify how Intel Xe driver handle compressed Tile4 framebuffers
on display with Xe2 hardware. Specifically, here is added support for
I915_FORMAT_MOD_4_TILED_XE2_CCS as a valid tiling mode for new framebuffers. 

This change remove unconditional decompression of Tile4 type framebuffers
on Xe2 display, as handling compressed versus not compressed framebuffers
have different requirement on discrete graphics than on integrated.

v2. rebase and change doucmentetaion render compression -> unified compression

Juha-Pekka Heikkila (3):
  drm/i915/display: Don't enable decompression on Xe2 with Tile4
  drm/fourcc: define Intel Xe2 related tile4 ccs modifiers
  drm/i915/display: allow creation of Xe2 ccs framebuffers
