V4L/DVB (12618): gspca: mr97310a add support for CIF and more VGA camera's

This patch adds supports for mr97310a camera's with CIF sensors (2 different
types) and for VGA mr97310a camera with a different sensor then supported
until now.

This patch also add support for controls for one of the 2 CIF sensors, this
was written by Thomas Kaiser <thomas@kaiser-linux.li>

* have assisted with their experience. Each of them has also helped by
