Re: [PATCH v2] powerpc/powernv/pci: use ifdef to avoid dead code

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

Move pnv_ioda_setup_bus_dma() under CONFIG_IOMMU_API to avoid dead code.

Doh! Thanks for the fix.
