amd-soundwire: add support for AMD generic legacy machine driver

alsa-project/alsa-ucm-conf pull request #478 was opened from perexg:

The card components string is similar to Intel's SOF driver like, so we can reuse sof-soundwire configuration and it is logical to reduce future maintenance, because the chips connected to soundwire bus are similar for multiple PCI bridges.

Example of the components string:

Components : ' cfg-amp:1 hs:rt722 spk:rt722 mic:rt722'
