ASoC: qdsp6: audioreach: add support for more port connections

AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.

This support is needed for more detailed graphs like ECNS, speaker
protection and so.
