mb/google/fatcat/var/fatcat: Workaround for codec enable with FPS

There is an issue where the codec enable signal is not working correctly
when FPS (Fingerprint Sensor) is enabled. This commit applies a
temporary workaround by using a dedicated GPIO pin for codec enable.

This allows the codec to function properly even when FPS is enabled,
preventing audio issues. A proper fix in hardware schematics will be
implemented in a future update.

BUG=b:390031369
TEST=Verified audio playback works with FPS being enabled.
