[media] cx25840 / cx23885: Fixing audio/volume regression
Since the conversion to subdev in Oct 2010 the audio controls have
not functioned correctly in the cx23885 driver. Passing values of
0-3f did not translate into meaningfull register writes. I've
converted the cx23885 driver to match the cx25840 volume control
definition and now audio is working reliably again.
