[PATCH net-next 10/10] net: mscc: ocelot: accept configuring bridge port flags on the NPI port

[Vladimir Oltean <vladimir.oltean@nxp.com>]

In order for the Felix DSA driver to be able to turn on/off flooding
towards its CPU port, we need to redirect calls on the NPI port to
actually act upon the index in the analyzer block that corresponds to
the CPU port module. This was never necessary until now because DSA
(or the bridge) never called ocelot_port_bridge_flags() for the NPI
port.
