Subject[PATCH] powerpc/powernv/pci: add ifdef to avoid dead code
From
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.

Fixes: dc3d8f85bb57 ("powerpc/powernv/pci: Re-work bus PE configuration")
