Alexey Kardashevskiy 9eda7d373e pci: Introduce helper to retrieve a PCI device's DMA address space 
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.

[aik: added inheritance from parent if iommu is not set for the current bus]
