I'm wondering why you choose to map everything at Xen boot time rather
than implementing PHYSDEVOP_pci_device_add to do the job?

This would allow us to re-use most of the interrupts/mmio decoding
provided in the device tree library. It would also avoid missing support
of cascade ranges/interrupt-map.
