mb/google/rex: Enable SoundWire codecs
Enable drivers for SoundWire codecs and define the topology in
the devicetree for the rex0 variant with the SoundWire daughter
board connected.
+------------------+ +--------------------+
| | | Headphone Codec |
| Intel Meteor Lake| +--->|Cirrus Logic CS42L42|
| SoundWire | | | ID 0 |
| Controller | | +--------------------+
| | |
| Link 0 +----+ +-------------------+
| | | Left Speaker Amp |
| Link 1 | +--->| Maxim MAX98363 |
| | | | ID 0 |
| Link 2 +----| +-------------------+
| | |
| Link 3 | | +-------------------+
| | | | Right Speaker Amp |
+------------------+ +--->| Maxim MAX98363 |
| ID 1 |
+-------------------+
This was tested by booting the firmware and dumping the SSDT table
to ensure that all SoundWire ACPI devices are created as expected with
the properties that are defined in coreboot under \_SB.PCI0:
HDAS - Intel Meteor Lake HDA PCI device
HDAS.SNDW - Intel Meteor Lake SoundWire Controller
HDAS.SNDW.SW00 - Cirrus Logic CS42L42 - Headphone Codec
HDAS.SNDW.SW20 - Maxim MAX98363 - Left Speaker Amp
HDAS.SNDW.SW21 - Maxim MAX98363 - Right Speaker Amp
BUG=b:269497731
TEST=Verified SSDT for SNDW in the OS. Playback and recording are also
validated on google/rex.
