[media] cx18: mmap() support for raw YUV video capture

Add support for mmap method streaming of raw YUV video on cx18-based
hardware, in addition to the existing support for read() streaming of
raw YUV and MPEG-2 encoded video.

[simon.farnsworth@onelan.co.uk: I forward-ported this from Steven's original work,
 done under contract to ONELAN. The original code is at
