commit e0146a108ce4d2c22b9510fd12268e3ee72a0161 upstream.
Compiling the nvlink stuff relies on the SPAPR_TCE_IOMMU otherwise there
are compile errors:
drivers/vfio/pci/vfio_pci_nvlink2.c:101:10: error: implicit declaration of function 'mm_iommu_put' [-Werror,-Wimplicit-function-declaration]
ret = mm_iommu_put(data->mm, data->mem);
As PPC only defines these functions when the config is set.
Previously this wasn't a problem by chance as SPAPR_TCE_IOMMU was the only
IOMMU that could have satisfied IOMMU_API on POWERNV.
Fixes: 179209fa1270 ("vfio: IOMMU_API should be selected")
