I agree, but I'm not sure the best way to organize a split. I'm not
doing anything with the Efika at the moment and I haven't dug into the
details of what needs to be done for AC97.

Here is the relevant excerpt, but it is not documented yet. I haven't
made any attempt encode the layout into the device tree (clocking, etc.)
