Revert "ALSA: hda - Fix pin-config of Gigabyte mobo"

This reverts commit c6b35874

.

It turned out that there are different pin configurations for this
PCI SSID, including multi-channel modes.  And more proper fix for
allowing line-out mutes will come up in 2.6.40 tree, so we won't need
this fixup any more there.
