Instead of registering qdev static properties on instance_init, register them as class properties, at qdev_class_set_props(). qdev_property_add_legacy() was replaced by an equivalent qdev_class_property_add_legacy() function. qdev_property_add_static(), on the other hand, can't be eliminated yet because it is used by arm_cpu_post_init().
