drivers/soundwire: Support Realtek ALC712 codec

Browse source 
Update SoundWire driver to support ALC712 audio codec.

reference datasheet: Realtek ALC712-VB-CG Rev. 0.24

BUG=b:378629979
TEST=emerge-fatcat coreboot
A sound can be heard from the speaker,
the test instructions are as follows:

amixer -c 0 cset name='rt712 OT23 L Switch' on
amixer -c 0 cset name=''rt712 OT23 R Switch' on
amixer -c 0 cset name='rt1320-1 OT23 L Switch' on
amixer -c 0 cset name='rt1320-1 OT23 R Switch' on
amixer -c 0 cset name='Speaker Switch' on

speaker-test -D hw:0,2 -c 2 -t sine -f 440
