libcamera: CameraSensor: Mention V4L2 in get/setControls()

Browse source 
The current CameraSensor interface for reading and writing controls
is currently based on V4L2 controls.

Mention that more clearly in the documentation and, while at it, re-sort
the documentation to match the methods declaration order.
