Documentation: networking: dsa: document the port_bridge_flags method
The documentation was already lagging behind by not mentioning the old
version of port_bridge_flags (port_set_egress_floods). So now we are
skipping one step and just explaining how a DSA driver should configure
address learning and flooding settings.
