which will be supported by Display13.

    - 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

v4: - Rebased, fixed merge conflict with new table-oriented
      format modifier checking(Stan)

      checks(Imre Deak)
    - Fixed I915_FORMAT_MOD_4_TILED to be 9 instead of 12
