net: dsa: bcm_sf2: Ensure correct sub-node is parsed
When the bcm_sf2 was converted into a proper platform device driver and used the new dsa_register_switch() interface, we would still be parsing the legacy DSA node that contained all the port information since the platform firmware has intentionally maintained backward and forward compatibility to client programs. Ensure that we do parse the correct node, which is "ports" per the revised DSA binding.
