Add the remaining Audio nodes on the SM8650-QRD board including:
- Qualcomm Aqstic WCD9395 audio codec on the RX & TX Soundwire interfaces
- WSA8845 Left & Right Speakers
- Link the WCD9395 Codec node to the WCD9395 USB SubSystem node to handle
  the USB-C Audio Accessory Mode events & lane swapping
- Sound card with routing for Speakers and Microphones
