media: Documentation: Document -ENXIO for VIDIOC_SUBDEV_S_ROUTING
Document that -ENXIO is returned when the user tries to set a routing
configuration not supported by the hardware (or rather the driver). The
documentation details the exact cases of this, besides -EINVAL that is
already documented for VIDIOC_SUBDEV_S_ROUTING.
