drm/amd/display: check cursor FB is linear
Previously we accepted non-linear buffers for the cursor plane. This
results in bad output, DC validation failures and oops.
Make sure the FB uses a linear layout in the atomic check function.
The GFX8- check is inspired from ac_surface_set_bo_metadata in Mesa.
The GFX9+ check comes from convert_tiling_flags_to_modifier.
