[media] hdpvr: update picture controls to support firmware versions > 0.15
Correctly sets the max/min/default values for the hdpvr picture controls. The reason the current values didn't cause a problem until now is because any firmware <= 0.15 didn't support them. The latest firmware releases properly support picture controls and the values in the patch are derived from the windows driver using SniffUSB2.0. Thanks to Devin Heitmueller for helping me.
