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