I implemented YUV422P in this version, and enforced width/height limits
to avoid crashes with certain applications.

Planar YUV422 allows vic (the video conference tool) to work with the
OV511. This mode has been implemented because:

1. It is closer to the camera native format, allowing other conversions
   to be done in userspace
2. vic wants data in YUV

The YUV422P code is very small. A patch to use vic in NTSC 640x480 instead
of the hardcoded PAL 768x576 is available at
http://helllabs.org/~claudio/ov511/vic/vic-2.8ucl-1.1.3-ntsc.patch
(The format selection in voc seems to be broken, I'll fix it later).

Best regards,
claudio
