Create the route in the .init_state() operation. Internal routing support requires stream support, so set the V4L2_SUBDEV_FL_HAS_STREAMS flag and switch formats and selection rectangles access from pads to streams. As the route is immutable, there's no need to implement the .set_routing() operation, and we can hardcode the sink and source stream IDs to 0.
