I'm not sure the macro name is ideal; the PCI host on aarch64/"virt"
emulates IO Ports (it's possible to allocate PCI IO resources on
"virt"). From patch#3, TARGET_HAS_IOPORT does not seem to extend to arm64.
Correct, aarch64 has memory-mapped pci io resources, they are not on a separate
ioport address space as for x86 and avr.
