Now that iommufd does not rely on dma-iommu.c for any purpose. We can
combine the dma-iommu.c iova_cookie and the iommufd_hwpt under the same
union. This union is effectively 'owner data' and can be used by the
entity that allocated the domain. Note that legacy vfio type1 flows
continue to use dma-iommu.c for sw_msi and still need iova_cookie.
