[PATCH v8 7/7] media: open.rst: add a notice about subdev-API on vdev-centric
The documentation doesn't mention if vdev-centric hardware control would have subdev API or not. Add a notice about that, reflecting the current status, where three drivers use it, in order to support some subdev-specific controls.
