I think the patch still needs a little improvement and discussion.
I've just done a second version, and tried out converting two
of the existing drivers to it, with good results.

We might want to add another set of callbacks for the first indirect
level, as that could help designware, mvebu and rcar at the minimum.
We then end up with 'root' config, 'port type 1' config and
'device type 0' config, with the first two falling back on the third
when unavailable.

I'm sending out what I have now.
