init_port was only being used to register sysfs attributes against the port kobject. Now that all users are creating static attribute_group's we can simply set the attribute_group list in the ops and the core code can just handle it directly. This makes all the sysfs management quite straightforward and prevents any driver from abusing the naked port kobject in future because no driver code can access it.
