cx88 default picture controls values

Marcin Rudowski wrote: 
This patch fixes default values for some picture controls:
 - brightness set to 50% by default (now is 0%)
 - hue set to 50% by default (now is 0%)
 - volume set to 0dB (now is -32dB)
and some left small fixes:
 - twice offset adding
 - balance didn't follow datasheet (bits[0:5] = attenuation;
   bit[6] = channel to provide attenuation)


This patch represents all pending fixes from old
"cx88_fix_controls_update.diff" sent "2006-01-21" by Ian.
It only doesn't include additional balance fix ("balance + volume <
-63dB" problem) and this will be covered in next patch.


I have applied this patch, and also the 2/2 for volume + balance dependency to my local copy and they are working fine for me. I've included my dmesg below for reference. Many thanks for the work on this.
Regards
Ian
