For pci ranges, you can add a new bus in dt_bues. So you won't need
specific code in domain_build.c and we will be able to use it later.
You can take a look to linux/drivers/of/address.c
Mapping interrupt should be OK. I don't see any reason that will fail
with the current code because IRQ are all under the GIC controller.
