alsa-info.sh: log SoundWire devices reported in ACPI
Track SoundWire devices reported in ACPI, this will help detect missing or invalid configurations. For now we only filter information from Realtek, Cirrus Logic and TI, based on the manufacturer ID of their devices. Example log for the classic RT711/RT1316x2/RT714 configuration. !!ACPI SoundWire Device Status Information !!--------------- Realtek 0x000030025d071101 Realtek 0x000331025d131601 Realtek 0x000230025d131601 Realtek 0x000130025d071401 As noted by reviewers, the script reports everything exposed in ACPI. In practice some of the devices listed may not be physically populated in hardware, or be listed as attached on a link that's disabled by the manager. The drivers can cope with this case, it's not technically an error.
