mb/google/dedede/var/sasukette: Add fw_config probe for ALC5682I-VD & VS
Update the `_HID` value of device in SSDT depending on the fw_config.
According to value of AUDIO_CODEC_SOURCE field in fw_config(SSFC) which
stored in CBI:
AUDIO_CODEC_ALC5682: _HID = "10EC5682" /* ALC5682I-VD */
AUDIO_CODEC_ALC5682I_VS: _HID = "RTL5682" /* ALC5682I-VS */
BUG=b:193623380
BRANCH=dedede
TEST=ALC5682I-VD or VS audio codec can work normally
