mb/google/zork/var/gumboz: Add fw_config probe for ALC5682-VD & VS

ALC5682-VD/ALC5682I-VS load different kernel driver by different hid
name. Update hid name and machine_dev depending on the AUDIO_CODEC_SOURCE
field of fw_config. Define FW_CONFIG bits 36 - 37 (SSFC bits 4 - 5)
for codec selection.

ALC5682-VD: _HID = "10EC5682"
ALC5682I-VS: _HID = "RTL5682"

BUG=b:
BRANCH=zork
TEST=ALC5682-VD/ALC5682I-VS audio codec can work
