drm/armada: use drm_plane_helper_check_state()
Use drm_plane_helper_check_state() to check the overlay plane state
rather than drm_plane_helper_check_update(), as:
(1) using drm_plane_helper_check_state() provides a better migration
path to atomic modeset
(2) it avoids needless copies of drm rectangle structures, and so is
more efficient.
