Following patches will change the way we communicate getting or setting
a port's attribute and use a blocking notifier to perform those tasks.
Prepare ocelot to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing
ocelot_port_attr_set() call.
