media: v4l2-core: Make the v4l2-core code enable/disable the privacy LED if present
Make v4l2_async_register_subdev_sensor() try to get a privacy LED associated with the sensor and extend the call_s_stream() wrapper to enable/disable the privacy LED if found. This makes the core handle privacy LED control, rather then having to duplicate this code in all the sensor drivers.
