[PATCH net-next 06/13] dpaa2-switch: create a separate dpaa2_switch_port_fdb_event() function

[Ioana Ciornei <ioana.ciornei@nxp.com>]

Create a separate dpaa2_switch_port_fdb_event() function that will only
handle the FDB related events. With this change, the
dpaa2_switch_port_event() notifier handler can be written in a way that
it's easier to follow.
