drm/amd/display: Attach only plane updates that actually changed
[Why & How]
Cache the last programmed dc_flip_addrs/dc_plane_info/dc_scaling_info in
dm_plane_state and carry them across atomic_duplicate_state. In
amdgpu_dm_commit_planes() attach each flip_addr/plane_info/scaling_info
surface update only when it differs from the cache (memcmp), so an
address-only flip sends no plane_info/scaling_info update and stays on the
FAMS2 offload path.
