Hi Florian

You have just removed all the actual DT parsing. So i would give this
a different name, and avoid the _ prefix.

We might want to call this _dsa_register_switch_legacy_sf2, since the
code only supports what is needed for your rather odd sf2 binding. It
does not appear to work for the generic DSA binding.

Maybe put this inside if config_enabled(CONFIG_NET_DSA_BCM_SF2)  {}?
