[PATCH v6 11/11] media: subdev: Improve s_stream documentation

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

Now that enable/disable_streams operations are available for
single-stream subdevices too, there's no reason to use the old s_stream
operation on new drivers. Extend the documentation reflecting this.
