This series introduces SMMU handling for PCIe passthrough on ARM. These patches
should be able to be upstreamed independently from the vPCI series [1]. See [2]
for notes about test cases.

v9->v10:
* drop iommu/arm: Add iommu_dt_xlate()
* see individual patches

v8->v9:
* see individual patches

v7->v8:
* no changes

v6->v7:
* drop ("xen/arm: don't pass iommu properties to hwdom for iommu-map")

v5->v6:
* don't revert ("xen/arm: Add cmdline boot option "pci-passthrough = <boolean>"")
* add ("xen/arm: enable dom0 to use PCI devices with pci-passthrough=no")

v4->v5:
* drop ("xen/arm: Improve readability of check for registered devices")
* drop ("xen/arm: Move is_protected flag to struct device")
* add ("xen/arm: don't pass iommu properties to hwdom for iommu-map")
* add ("xen/arm: Fix mapping for PCI bridge mmio region")
* revert ("xen/arm: Add cmdline boot option "pci-passthrough = <boolean>"")
* add ("xen/arm: Map ITS doorbell register to IOMMU page tables.")
* fix test case #1 with PCI device in dom0

v3->v4:
* split a change from ("xen/arm: Move is_protected flag to struct device") into
  a new separate patch
* see individual patches for further details

v2->v3:
* drop "pci/arm: Use iommu_add_dt_pci_device()"
* drop "RFC: pci/arm: don't do iommu call for phantom functions"
* move invocation of sideband ID mapping function to add_device()
  platform_ops/iommu_ops hook
