ALSA: ice1724: Fix surround on Chaintech AV-710
Fix the num_total_dacs setting for Chaintech AV710. The existing comment that only PSDOUT0 is connected is correct, but since the card is using packed AC97 mode to send 6 channels to the codec, num_total_dacs should be set to 6 and not 2. This allows 6-channel surround to work. Also clarify a comment regarding the additional WM8728 codec on this card (it's connected to the SPDIF output and always receives the same data).
