[media] saa7146: fix querycap, vbi/video separation and g/s_register

Browse Source 
The querycap ioctl returned an incorrect version number and incorrect
capabilities (mixing up vbi and video caps).

The reason for that was that video nodes could do vbi activities: that
should be separated between the vbi and video nodes.

There were also a few minor problems with dbg_g/s_register that have
been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.
