VFIOContainerBase was made a QOM interface because we believed that a QOM object would expose all the IOMMU backends to the QEMU machine and human interface. This only applies to user creatable devices or objects. Change the VFIOContainerBase nature from interface to object and make the necessary adjustments in the VFIO_IOMMU hierarchy.
