Oops, copy-paste failure here, nuss was for the am65-cpsw-nuss driver,
maybe "-nuss" could be simply deleted from the commit message on "apply"...

Well, yes, they re-invent the wheel, mimicking the DSA infrastructure
without using it. CPSW is a switch, as the name suggests, but the
effort has not been spent to bring it to DSA home ;-)

in DSA terms, and dsa_register_switch() would for sure do it...
