dsa/mv88e6131: fix unknown multicast/broadcast forwarding on mv88e6085 The 88e6085 has a few differences from the other devices in the port control registers, causing unknown multicast/broadcast packets to get dropped when using the standard port setup. At the same time update kconfig to clarify that the mv88e6085 is now supported.
