soc/intel/tigerlake: Make audio devices scan the bus

The audio devices are currently set to enable static devices at their
own level, but in order to supported nested SoundWire devices these
drivers must instead use scan_static_bus.  Without this change the
device tree code will not look at children of these devices.

After this change the audio device can have nested devices:

device pci 1f.3 on
  chip drivers/intel/soundwire
    device generic 0 on end
  end
end
