V4L/DVB (12073): gspca_ov519: limit ov6630 qvif uv swap fix to ov66308AF

The fix for the UV swapping in qcif mode with the ov6630, which I did
to fix this issue on a ov518 cam with an ov66308AF, causes UV swapping in
qcif with another cam of mine with the ov518 and an ov66308AE, so this
patch changes the code to differentiate between the ov66308AF and other
ov6630 versions, and restricts the UV swap fix to the ov66308AF.
