Extend the PipeWire recipe to add platform-specific ALSA configuration

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?


Only these settings are AM62D specific here:

 * api.alsa.path
 * audio.channels and position (could be modified as needed)

Others could be left to default (most are redundant as they point to default values and only added for reference) PipeWire: Index <https://docs.pipewire.org/page_config_xref.html> I will experiment with other parameters later to see if they result in any performance improvement.

Primary goal was to add 8-channel configuration for AM62D codec otherwise AM62D also works with the default stereo config. Same case for other platforms they can use default stereo config or follow AM62D config for multichannel (depending on board codec)
