drm/i915/mtl: Add support of Tile4 to MTL

We have some Tile4 tests now skipping, which were
supposed to be working. So lets make them work, by
adding display_ver 14 as supported.

v2: - Remove "14" for Tile 4 CCS formats, as they
      seem to be not supported by MTL(Juha-Pekka Heikkila)
    - For generic Tile 4, the opposite - lets use -1
      in order to make sure all the next gens support it by
      default(Juha-Pekka Heikkila)
