Recent sn9c20x driver written by microdia project
(http://groups.goolge.com/group/microdia) introduce new output format -
sn9c20x-i420. This format is actually scrambled yuv420, so it's very easy and
fast to convert it to yuv420. This patch adds sn9c20x-i420 decoder to the
libv4l-0.5.7
This decoder is much faster than jpeg one (sn9c20x supports JPEG too):
sn9c20x-i420 decoder eats only 10% of 1GHz CPU at 640x480x25fps vs 40% of
1GHz CPU in jpeg at same frame size/rate.
This format should be preffered for sn9c20x, because sn9c20x driver supports
SBGGR8 too, so it should go before SBGGR8 in supported_src_pixfmts.
