Great.

Agreed.

Things started out here, but as the number of subsystems and
associated bindings grew it became evident that binding specific
things should go with the subsystems. I also have a secret goal to
eliminate drivers/of. Don't tell anyone.

of_net should probably move, just no one has had the itch to do it.
PCI is a bit special and somewhat tied into the rest of the core.
