soc/intel/braswell: Adjust status of IOSF ACPI object
Neither Windows nor mainline Linux make use of IOSF on the Braswell
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/edgar
