mb/google/nissa: Add AUDIO_CONFIG in fw_config

The codec alc5650 has different setting from other amp codec in
depthcharge. Since nissa has a single shared depthcharge target,
add the fw_config field to allow different audio_configs.
(refer to chromium:4983866)

BUG=b:307410704
TEST=With depthcharge change, set fw_config and gbb flags on craaskana
     and check beep sound on firmware screen is workable.
