drm/amd/display: Add Gfx Base Case For Linear Tiling Handling

[Why]
Post-driver cases always use linear tiling yet there is no dedicated
Gfx handling for this condition.

[How]
Add DcGfxBase/DalGfxBase to gfx version enums and set tiling to linear
when it is used. Also, enforce the use of proper tiling format as tiling
information is used.
