From: Arnd Bergmann <arnd@arndb.de>

The tegra variant of smmu-v3 now uses the iommufd mmap interface but
is missing the corresponding import:

ERROR: modpost: module arm_smmu_v3 uses symbol _iommufd_object_depend from namespace IOMMUFD, but does not import it.
ERROR: modpost: module arm_smmu_v3 uses symbol iommufd_viommu_report_event from namespace IOMMUFD, but does not import it.
ERROR: modpost: module arm_smmu_v3 uses symbol _iommufd_destroy_mmap from namespace IOMMUFD, but does not import it.
ERROR: modpost: module arm_smmu_v3 uses symbol _iommufd_object_undepend from namespace IOMMUFD, but does not import it.
ERROR: modpost: module arm_smmu_v3 uses symbol _iommufd_alloc_mmap from namespace IOMMUFD, but does not import it.
