This allows us to remove a call to device_class_set_parent_reset(), replacing it with the three-phase equivalent resettable_class_set_parent_phases(). Removing all the device_class_set_parent_reset() uses will allow us to remove some of the glue code that interworks between three-phase and legacy reset. This is a simple conversion, with no behavioural changes.
