mb/google/fatcat/var/kinmen: Add AUDIO_UNKNOWN and probe for ALC721

Browse source 
This commit enhances the Kinmen variant of the Fatcat mainboard by
introducing an `fw_config` field for AUDIO. This field includes an
`AUDIO_UNKNOWN` option, providing a clear state when no specific audio
configuration is selected or known.

Furthermore, a probe statement for `AUDIO_ALC721_SNDW` has been added
to the `hda` device. This ensures that the system can correctly identify
and initialize the Realtek ALC721 audio codec when present.

These changes improve the flexibility and accuracy of audio
configuration and detection for the Kinmen board.

BUG=b:430205874
TEST=Able to boot google/kinmen to UI without valid Audio configuration.
