drm_plane_helper_check_update() needs to account for the plane rotation for correct clipping/scaling calculations. Do so.
There was an earlier attempt [1] to add this into intel_check_primary_plane() but I requested that it'd be put into the helper instead. An updated patch never materialized AFAICS, so I went ahead and cooked one up myself.
