This looks very suspicious, pci_addr is not unique across all domains,
so there is no way to convert from a pci_addr to the virtual IO
address without knowing the domain number as well.
I would like to see it be:
port = pci_address_to_pio(range->cpu_addr);
cpu_addr is unique across all domains.
Looking at the microblaze and PPC versions I think the above version
is actually correct (assuming io_base_phys is the CPU address of the
IO window)
