IOMMUFD designs two iommu_domain pointers to represent two stages. The S1
iommu_domain (IOMMU_DOMAIN_NESTED type) represents the Context Descriptor
table in the user space. The S2 iommu_domain (IOMMU_DOMAIN_UNMANAGED type)
represents the translation table in the kernel, owned by a hypervisor.
So there comes to no use case of the ARM_SMMU_DOMAIN_NESTED. Drop it, and
use the type IOMMU_DOMAIN_NESTED instead.
