Fix cursor plane didn't update issue by below modification: 1. Remove plane_helper_funcs->atomic_update(plane, state) in mtk_drm_crtc_async_update. 2. Add mtk_drm_update_new_state into mtk_plane_atomic_async_update to update the cursor plane by current plane state hook and add it into mtk_plane_atomic_update to update others plane by the new_state.
