Hence, PCI libqos tests cannot be run with aarch64 binary. This series brings the pieces needed to be able to run PCI tests with the aarch64 binary: a generic-pcihost driver node gets instantiated by the machine. This later contains a pci-bus-generic driver which produces a pci-bus interface. Then all tests consuming the pci-bus interface can be run with the libqos arm virt machine. One of the first goal was to be able to run the virtio-iommu-pci tests as the virtio-iommu was initially targetting ARM and it was awkard to be run the test with the pc machine. This is now possible. Only the tests doing hotplug cannot be run yet as hotplug is not possible on the root bus. This will be dealt with separately by adding a root port to the object tree.
