dpaa2-switch: refactor the egress flooding domain setup
Extract the code that determines the list of egress flood interfaces for
a specific flood type into a new function -
dpaa2_switch_fdb_get_flood_cfg().
This will help us to not duplicate code when the broadcast and
unknown ucast/mcast flooding domains will be individually configurable.
