[ALSA] Added support for Terratec PHASE 22

ICE1712 driver,ICE1724 driver
I've struggled for a couple of days with Terratec Phase 22 card.
Chips used on it are well known but the combination is somehow unique.
Phase 88 should have been similar...  but it actually uses 1712
instead of 1721 (Envy24HT-S). So here is the patch against release
1.0.8 that adds Phase 22 to ice1724. I've tested only analog part
(balances 1/4 TRS in and outs).
