net: dsa: felix: restore multicast flood to CPU when NPI tagger reinitializes
ocelot_init sets up PGID_MC to include the CPU port module, and that is
fine, but the ocelot-8021q tagger removes the CPU port module from the
unknown multicast replicator. So after a transition from the default
ocelot tagger towards ocelot-8021q and then again towards ocelot,
multicast flooding towards the CPU port module will be disabled.
