AMD SoundWire machine driver code refactor

Merge series from Vijendar Mukunda <[email protected]>:

This patch series moves common Soundwire endpoint parsing and dai
creation logic to common placeholder from Intel generic SoundWire
machine driver code to make it generic. AMD SoundWire machine driver
code is refactored to use these functions for SoundWire endpoint
parsing and dai creation logic.
