[0/6] ASoC: soc-acpi: add support for SoundWire-based machines

Message

SoundWire support on Intel platforms relies on ACPI _ADR fields
exposed in DSDT tables, with a 64-bit value defining which link a
Slave device is connected to and its partId/manufacturerID/uniqueID.

The existing definitions based on a globally-visible _HID used for
I2C/I2S are no longer sufficient and need to be extended to detect
during the probe steps which machine driver should be selected.

This patchset adds the structure changes, and a set of static tables
already used by Intel developers and customers. These tables are
provided ahead of time, but they will only be used once all
SoundWire-related parts are merged upstream and SoundWire is enabled
in the builds.

For reference, the complete set of 100+ patches required for SoundWire
on Intel platforms is available here:
