So let's just introduce a simpler version that skips all that. Ideally we could also skip the __setplane_check() as drm_atomic_plane_check() already checks for everything, but the legacy cursor/"async" .update_plane() tricks bypass that so we still need to call __setplane_check(). Toss in a FIXME to remind someone to clean this up later.
