media: v4l2-subdev: Document that routing support depends on streams
Routing support, through the subdev .set_routing() operation, requires
the subdev to support streams. This is however not clearly documented
anywhere. Fix it by expanding the operation's documentation to indicate
that subdevs must set the V4L2_SUBDEV_FL_STREAMS flag.
