ALSA: hda - Fix GPIO for Acer Aspire 3830TG
commit 4a4370442c996be0fd08234a167c8a127c2488bb upstream. Acer Aspire 3830TG seems requiring GPIO bit 0 as the primary mute control. When a machine is booted after Windows 8, the GPIO pin is turned off and it results in the silent output. This patch adds the manual fixup of GPIO bit 0 for this model.
