The 4A default configuration needs to be changed to reflect a default viable option.

As 4a will accept to load more than than required, the simple temporary solution is to create a valid default for Intel and a valid default for Renesas.

In file 

/usr/agl-service-audio-4a/ahl-agl-service-audio-4a-config.json

e.g for Intel 

  "hal_list": ["usb-audio", "intel-hda", "intel-hda"]
