net: dsa: add switch notifier
Add a notifier block per DSA switch, registered against a notifier head in the switch fabric they belong to. This infrastructure will allow to propagate fabric-wide events such as port bridging, VLAN configuration, etc. If a DSA switch driver cares about cross-chip configuration, such events can be caught.
