A slave device will now notify the switch fabric once its port is
bridged or unbridged, instead of calling directly its switch operations.
This code allows propagating cross-chip bridging events in the fabric.

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.
