[media] uvcvideo: Remove deprecated UVCIOC ioctls
The UVCIOC_CTRL_ADD, UVCIOC_CTRL_MAP_OLD, UVCIOC_CTRL_GET and UVCIOC_CTRL_SET ioctls are deprecated and were scheduled for removal for v2.6.42. As v2.6.42 == v3.2, remove them.

-What: Support for UVCIOC_CTRL_ADD in the uvcvideo driver
-When: 3.2
-Why: The information passed to the driver by this ioctl is now queried
- dynamically from the device.

-
-----------------------------
-
-What: Support for UVCIOC_CTRL_MAP_OLD in the uvcvideo driver
-When: 3.2
-Why: Used only by applications compiled against older driver versions.
- Superseded by UVCIOC_CTRL_MAP which supports V4L2 menu controls.

-What: Support for UVCIOC_CTRL_GET and UVCIOC_CTRL_SET in the uvcvideo driver

-Why: Superseded by the UVCIOC_CTRL_QUERY ioctl.
-Who: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

What: Support for driver specific ioctls in the pwc driver (everything
defined in media/pwc-ioctl.h)
When: 3.3
