drm/imx: ipuv3-plane: let drm_plane_state_to_ubo/vbo handle chroma subsampling other than 4:2:0
To support 4:2:2 or 4:4:4 chroma subsampling, divide the x/y offsets in drm_plane_state_to_ubo/vbo only if necessary for the given pixel format. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Acked-by: Liu Ying <gnuiyl@gmail.com>
