[media] cx88: fix a number of v4l2-compliance violations 

- missing COMPRESSED flag for MPEG formats
- set colorspace
- set sizeimage
- add tuner index checks
- setup the frequency ranges correctly
- add missing g_chip_ident ioctl
- fix audmode handling
- don't handle vbi formats on a video node and vice versa.

cx88 now passes the v4l2-compliance tests.
