mb/google/fatcat/var/francka: Add AUDIO_UNKNOWN and audio probes

Browse source 
This commit introduces an `AUDIO_UNKNOWN` option to the `fw_config` for
the Francka variant of the Fatcat mainboard. This allows for a default
or fallback state when a specific audio configuration isn't known or
desired.

Additionally, this change introduces audio probe statements that allow
the system to boot successfully even if `FW_CONFIG` is set to
`AUDIO_UNKNOWN`, effectively disabling the audio controller in such
cases.

This prevents boot failures when an unsupported or unknown audio codec
is selected, improving system robustness.

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