Simon Farnsworth 1bf5842fe3 [media] cx18: Clean up mmap() support for raw YUV
The initial version of this patch (commit
d5976931639176bb6777755d96b9f8d959f79e9e) had some issues:

 * It didn't correctly calculate the size of the YUV buffer for 4:2:2,
   resulting in capture sometimes being offset by 1/3rd of a picture.

 * There were a lot of variables duplicating information the driver
   already knew, which have been removed.

 * There was an in-kernel format conversion - libv4l can do this one,
   and is the right place to do format conversions anyway.

 * Some magic numbers weren't properly explained.

Fix all these issues, leaving just the move from videobuf to videobuf2
to do.
