drm/i915/dg2: Tile 4 plane format support
Tile4 in bspec format is 4K tile organized into
64B subtiles with same basic shape as for legacy TileY
which will be supported by Display13.
v2: - Moved Tile4 associating struct for modifier/display to
the beginning(Imre Deak)
- Removed unneeded case I915_FORMAT_MOD_4_TILED modifier
checks(Imre Deak)
- Fixed I915_FORMAT_MOD_4_TILED to be 9 instead of 12
(Imre Deak)
v3: - Rebased patch on top of new changes related to plane_caps.
- Added static assert to check that PLANE_CTL_TILING_YF
matches PLANE_CTL_TILING_4(Nanley Chery)
- Fixed naming and layout description for Tile 4 in drm uapi
header(Nanley Chery)
v4: - Extracted drm_fourcc changes to separate patch(Nanley Chery)
