You can disable that, it's meant to be used for speech recognition I think.
This device will be enabled after initialization in the FSP, regardless of the settings in the device tree. I do not yet know how to disable this using the FSP options. Maybe try to disable this device in the DEVEN register (Device Enable - Offset: [B:0, D:0, F:0] + 54h)?
