drm/i915/dg2: Tile 4 plane format support

Browse source 
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)
