Drop switchdev_ops.switchdev_port_attr_get and _set. Drop the uses of
this field from all clients, which were migrated to use switchdev
notification in the previous patches.

Add a new function switchdev_port_attr_notify() that sends the switchdev
notifications SWITCHDEV_PORT_ATTR_GET and _SET.

Update switchdev_port_attr_get() to dispatch to this new function. Drop
__switchdev_port_attr_set() and update switchdev_port_attr_set()
likewise.
