This defines new QOM object - IOMMUMemoryRegion - with MemoryRegion as a parent. This moves IOMMU-related fields from MR to IOMMU MR. However to avoid dymanic QOM casting in fast path (address_space_translate, etc), this adds an @is_iommu boolean flag to MR and provides new helper to do simple cast to IOMMU MR - memory_region_get_iommu. The flag is set in the instance init callback. This defines memory_region_is_iommu as memory_region_get_iommu()!=NULL. This switches MemoryRegion to IOMMUMemoryRegion in most places except the ones where MemoryRegion may be an alias.
