[RFC PATCH v2 124/137] hw/i386/amd_iommu: Parent internally-created AMDVI-PCI under the IOMMU

When the AMD IOMMU creates its own PCI companion device (no pci-id
supplied by the user), parent it under the sysbus IOMMU so it has a
canonical path at <iommu>/pci.  The user-supplied path already
parents via -device.
