mb/google/volteer/var/copano: Add fw_config probe for ALC5682-VD & VS 

ALC5682-VD/ALC5682I-VS load different kernel driver by different _HID
name. Update hid name depending on the AUDIO_CODEC_SOURCE field of
fw_config. Define FW_CONFIG bits 41 - 43 (SSFC bits 9 - 11)
for codec selection.

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

BUG=b:218245715
BRANCH=volteer
TEST=ALC5682-VD/ALC5682I-VS audio codec can work
