Commit dc3d8f85bb57 ("powerpc/powernv/pci: Re-work bus PE configuration") removed a couple pnv_ioda_setup_bus_dma() calls. The only remaining calls are behind CONFIG_IOMMU_API. Thus builds without CONFIG_IOMMU_API see: arch/powerpc/platforms/powernv/pci-ioda.c:1888:13: error: 'pnv_ioda_setup_bus_dma' defined but not used
Add CONFIG_IOMMU_API ifdef guard to avoid dead code.
