A PCI device's DMA address space (possibly an IOMMU) is returned by a method on the PCIBus. At the moment that only has one caller, so the method is simply open coded. We'll need another caller for VFIO, so this patch introduces a helper/wrapper function. If IOMMU is not set, the pci_device_iommu_address_space() function returns the parent's IOMMU skipping the "bus master" address space as otherwise proper emulation would require more effort for no benefit.
