drm/i915/dg2: Tile 4 plane format support
TileF(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: - Fixed wrong case condition(Jani Nikula)
- Increased I915_FORMAT_MOD_F_TILED up to 12(Imre Deak)
v3: - s/I915_TILING_F/TILING_4/g
- s/I915_FORMAT_MOD_F_TILED/I915_FORMAT_MOD_4_TILED/g
- Removed unneeded fencing code
v4: - Rebased, fixed merge conflict with new table-oriented
format modifier checking(Stan)
- Replaced the rest of "Tile F" mentions to "Tile 4"(Stan)
v5: - Still had to remove some Tile F mentionings
- Moved has_4tile from adlp to DG2(Ramalingam C)
- Check specifically for DG2, but not the Display13(Imre)
v6: - 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)
v7: - Fixed display_ver to { 13, 13 }(Imre Deak)
- Removed redundant newline(Imre Deak)
