    hw/acpi/piix4.c: convert static variables to static class properties

    The majority of the properties in piix4_pm_add_properties() are assigned to
    static variables and so can be converted to static class properties. Introduce
    piix4_pm_add_class_properties() to hold the static properties and soon all
    other class props after they have been converted from object props.
