Public bug reported:

[SRU Justifications]

[Impact]
Modern Intel platforms (RPL, MTL, LNL...etc) connect audio codecs on Soundwire instead of HDA, but the soundwire devices are not well reflected on the alsa-info report. In order to meet the increasing demands for SoundWire debugging, we must enable alsa-info to provide more information about SoundWire.

[Fix]
Backport the upstream commit cc0bcef81389 ("alsa-info.sh: log SoundWire devices reported in ACPI"). The reported information can reflect which soundwire devices are connected and which soundware link the device connects to. It's quite sufficient for what driver should be ready and what tplg/firmware file should be loaded. 

[Test Case]
1. Find a machine with (RTK/Cirrus/TI) Soundwire audio device. 
2. Install the new alsa-utils debian package
3. Execute `alsa-info` to generate the report
4. Check if the section "ACPI SoundWire Device Status Information" exists in the output report. 

[Where problems could occur]
It's simply an additional soundwire information when ACPI exposed the soundwire device. The risk for regression is low.
