USB-Audio: ALC4080: Update NVIDIA DGX front mic jack name

The ALC4080 codec in NVIDIA DGX exposes the front microphone as the
dedicated "Front Mic - Input Jack" terminal. Use this terminal instead
of the indexed "Mic - Input Jack",index=1 control, which PipeWire
rejects and therefore cannot use to track front-mic availability.

This patch redefines Mic1 according to the codec firmware with the
front mic's terminal name.
