The .probe dsa_switch_ops is part of the legacy code, we may want to
wrap it in a CONFIG_NET_DSA_LEGACY check as well.

We need to have it enabled by default, otherwise we'll miss errors when
touching the code shared by both legacy and new bindings.

the dsa_legacy_fdb_{add,del} routines are "legacy" in terms of FDB
handling, not in terms of DSA bindings, we must keep them.
