drm/amd/display: Fold GFX6-8 tiling and modifier tests

Browse source

[WHAT]
Reduce the four KUnit tests for
amdgpu_dm_plane_fill_gfx6_tiling_info_from_modifier() to one, and the
three for amdgpu_dm_plane_calc_gfx6_mod() to one.

[HOW]
Build the linear, rejected, 1D tiled and 2D tiled modifiers as locals
and decode them in sequence, and drive the micro tiled, GFX7-8 and GFX6
modifier calculations from two devices inside a single test.
