  This patch set implements UVC v1.5 regioin of interest using V4L2
control API.

ROI control is consisted an auto control with type bitmask and a
rectangle control with a newly added type V4L2_CTRL_TYPE_RECT.

V4L2_CTRL_WHICH_MIN/MAX_VAL is added to support the rectangle control.

A rectangle control is also added to the vivid test driver.

Tested on two different usb cameras using v4l2-ctl and calling ioctls.
