drm: rcar-du: Rework plane setup code
Now that the plane setup code isn't called outside of the plane implementation, it can be simplified by merging the rcar_du_plane_compute_base() and rcar_du_plane_update_base() functions. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
