The videodev2.h file contains, among other things, defines that point
to the control properties of video devices.

For the standard video controls, there is a V4L2_CID_BASE define for
the base, and a pointer to the last control ID plus 1 named
V4L2_CID_LASTP1.
This allows automatic, version independent enumeration of the controls.

There are other controls which are specific to the camera class
devices. While there is a V4L2_CID_CAMERA_CLASS_BASE define, there was
none for the last one.
As a result it was not possible to do an enumeration of the controls
of that class. This patch corrects this by adding a
V4L2_CID_CAMERA_CLASS_LASTP1 define.
