drm/amd/display: Fold GFX9 tiling info tests

Browse source

[WHAT]
Reduce the two KUnit tests for
amdgpu_dm_plane_fill_gfx9_tiling_info_from_device() to one, and the
three for amdgpu_dm_plane_fill_gfx9_tiling_info_from_modifier() to one.

[HOW]
Reprogram the device configuration and re-run the helper in sequence
inside a single test per function, so the pre-10.3, 10.3-and-later,
linear, pre-NV and NV-and-later cases all stay covered.
