powerpc/powernv: Fix build with IOMMU_API=n 



The builds breaks when IOMMU_API=n, eg. skiroot_defconfig:

  arch/powerpc/platforms/powernv/npu-dma.c:96:28: error: 'get_gpu_pci_dev_and_pe' defined but not used
  arch/powerpc/platforms/powernv/npu-dma.c:126:13: error: 'pnv_npu_set_window' defined but not used

Fixes: b4d37a7b ("powerpc/powernv: Remove unused pnv_npu_try_dma_set_bypass() function")
