soc/intel/baytrail: Adjust status of IOSF ACPI object 

Neither Windows nor mainline Linux make use of IOSF on the Baytrail
platform, so adjust the ACPI status return value based on
CONFIG(CHROMEOS) to prevent an unknown device being listed in Windows
device manager.

TEST=build/boot Win11, Linux 6.2 on google/swanky
