net: dsa: Introduce driver for NXP SJA1105 5-port L2 switch
At this moment the following is supported: * Link state management through phylib * Autonomous L2 forwarding managed through iproute2 bridge commands. IP termination must be done currently through the master netdevice, since the switch is unmanaged at this point and using DSA_TAG_PROTO_NONE.
