The PCI core supports an offset per aperture nowadays but our arch code still has a single offset per host bridge representing the difference betwen CPU memory addresses and PCI MMIO addresses. This is a problem as new machines and hypervisor versions are coming out where the 64-bit windows will have a different offset (basically mapped 1:1) from the 32-bit windows. This fixes it by using separate offsets. In the long run, we probably want to get rid of that intermediary struct pci_controller and have those directly stored into the pci_host_bridge as they are parsed but this will be a more invasive change.
