mb/asus/p8z77-m: Support AC97 front audio panel
Add a nvram option for front audio panel type.
If it is set to AC97, reprogram front line out and microphone
pins to match vendor firmware under same configuration.
TEST=On asus/p8z77-m housed in an AOpen H340D case with an AC97
front audio panel, front panel line out port is now available as
headphone port in Fedora 39 with this patch applied and option
set correctly. And it works. Without the patch (or with this option
set to HD Audio), front audio ports are completely inoperable.
