I believe you will need an "interrupt-map" property here, to map the host
interrupts to the INTA-INTD lines of the attached devices.

I'm not sure whether we want to have a device_type="pciex" property here.
powerpc and sparc seem to use that information, to distinguish a pcie
bus from pci or cardbus.
