media: subdev: Support non-routing subdevs in v4l2_subdev_s_stream_helper()

Browse Source 
At the moment v4l2_subdev_s_stream_helper() only works for subdevices
that support routing. As enable/disable_streams now also works for
subdevices without routing, improve v4l2_subdev_s_stream_helper() to do
the same.
