Extend the PipeWire recipe to add platform-specific ALSA configuration
and service file. Service file added to start PipeWire as a system
service with proper socket dependency.
Add sink and source configuration for 8-channel audio playback and
capture on the AM62D2EVM as the default configuration is 2-channel.

Are these settings truly am62d specific? And do any of the other
platforms need special configs?
For all of the other platforms will they work without configs like these?
