The V4L2Device class uses V4L2ControlList as a controls container for the getControls() and setControls() operations. Having a distinct container from ControlList will makes the IPA API more complex, as it needs to explicitly transport both types of lists. This will become even more painful when implementing serialisation and deserialisation. To simplify the IPA API and ease the implementation of serialisation and deserialisation, replace usage of V4L2ControlList with ControlList in the V4L2Device (and thus CameraSensor) API. The V4L2ControlList class becomes a thin wrapper around ControlList that slightly simplifies the creation of control lists for V4L2 controls, and may be removed in the future.
