[PATCH] ALSA: hda/realtek: add quirk for ASUS UM6702RC

[PATCH] ALSA: hda/realtek: add quirk for ASUS UM6702RC

[Zhang Heng]

The sound card of this machine cannot adjust the volume, it can only
be 0 or 100%. The reason is that the DAC with pin 0x17 is connected
to 0x06. Testing found that connecting 0x02 can fix this problem.
