ALSA: hda - Add add multi-streaming playback for AD1988

Attached a patch which add a new model to support multi-streaming
playback for ad1988.

playback another stereo stream through the front panel headphone on
device 2 while playback through the speakers connected to rear panel
on device 0 at the same time.

Tested with ad1988a rev2 codec on asus P5B-V motherboard.
