[PATCH 7/9] drm/rockchip: Use drm_plane_helper_check_state()

[ville.syrj...@linux.intel.com]

From: Ville Syrjälä <ville.syrj...@linux.intel.com>

Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.

Rockchip looks to handling plane clipping rather well already
(unlikje most arm drm drivers) so there are no function changes
here.
