Driver core changes under the guise of only PCI changes?  Please no.

Break this series out properly, get the driver core stuff working FIRST,
then show how multiple busses will work with them (i.e. you usually need
3 to know if you got it right).

I'm guessing you will need/want PCI, platform, and something else?
