[ALSA] ice1712 - disable unused ADCs & DACs on DMX6fire 

Modules: ICE1712 driver

Change the value written to hardware configuration register of envy24 chip
in the case of Terratec DMX6fire to restrict the active ADCs & DACs to 6.

Also add the dxr_enable module option to eventually leave the old behaviour
when user requests.
