drm/amd/display: Test accepted plane atomic check

Browse source

[WHAT]
Add a KUnit test for amdgpu_dm_plane_atomic_check() covering the
success path taken once DC validation accepts the plane.

[HOW]
Extend the shared atomic-check fixture with a resource pool that has
no validate_plane callback, so dc_validate_plane() only inspects the
source and destination rectangles.
