mb/google/volteer: Add SoundWire codecs to volteer variant
Enable drivers for SoundWire codecs and define the topology in
the devicetree for the volteer variant with the SoundWire daughter
board connected.
+------------------+ +-------------------+
| | | Headphone Codec |
| Intel Tigerlake | +--->| Realtek ALC5682 |
| SoundWire | | | ID 1 |
| Controller | | +-------------------+
| | |
| Link 0 +----+ +-------------------+
| | | Left Speaker Amp |
| Link 1 +----+--->| Maxim MAX98373 |
| | | | ID 3 |
| Link 2 | | +-------------------+
| | |
| Link 3 | | +-------------------+
| | | | Right Speaker Amp |
+------------------+ +--->| Maxim MAX98373 |
| ID 7 |
+-------------------+
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 Tigerlake HDA PCI device
HDAS.SNDW - Intel Tigerlake SoundWire Controller
HDAS.SNDW.SW01 - Realtek ALC5682 - Headphone Codec
HDAS.SNDW.SW13 - Maxim MAX98373 - Left Speaker Amp
HDAS.SNDW.SW17 - Maxim MAX98373 - Right Speaker Amp
