From: Stanislav Lisovskiy <stanislav.lisovs...@intel.com>
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: - Fixed the has_4tile addition (Ram)
