iommufd/viommu: Add IOMMU_VIOMMU_ALLOC ioctl
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.
IOMMU driver wanting to support vIOMMUs must define its IOMMU_VIOMMU_TYPE_
in the uAPI header and implement a viommu_alloc op in its iommu_ops.
