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)
