    southbridge/hudson: Initialize ACPI IO ports separate of FADT
    
    The ACPI IO ports, and the respective SMI (for HAVE_SMI_HANDLER), were
    initialized when the FADT table was written. This works well on a cold
    boot, but the ACPI ports are not initialized on S3 resume, as ACPI
    tables are not written. This will not work on S3 resume if the default
    ports are not what we set them, or if AGESA sets them to some other
    value.
    
    To solve this, move the port configuration to southbridge chip init.
