ArmVirtualizationPkg/PciHostBridgeDxe: IO space is emulated with MMIO
There is no IO space on ARM, and there are no special instructions that
access it. QEMU emulates the IO space for PCI devices with a special MMIO
range. We're ready to use it at this point, we just have to switch the
Io(Read|Write)(8|16|32) primitives to their MMIO counterparts, because in
"MdePkg/Library/BaseIoLibIntrinsic/IoLibArm.c", the IO primitives
correctly ASSERT (FALSE).
