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.
