Only PIIX4 provides this property while PIIX3 doesn't.

Unlike initialize() methods, init() methods allow for device-specific
quirks without having to call the parent method. So move the creation of
the property into PIIX4's init() method as a preparation of the code
merge and the subsequent cleanup of the realize methods.
