[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.
