V4L/DVB (10434): cx18: Smarter verification of CX18_AUDIO_ENABLE register writes
The CX18_AUDIO_ENABLE register usually never reads back what was just written
under normal circumstances. Perform better checking that a write went to the
register as expected with a specification of what bits to verify.
