why highlight 'driver-
Add a new ioctl for user space to do a vIOMMU allocation. It must be based
on a nesting parent HWPT, so take its refcount.
If an IOMMU driver supports a driver-managed vIOMMU object, it must define
its own IOMMU_VIOMMU_TYPE_ in the uAPI header and implement a viommu_alloc
op in its iommu_ops.
