#     powerpc/powernv: Remove unused pnv_npu_try_dma_set_bypass() function
#     
#     Neither pnv_npu_try_dma_set_bypass() nor the pnv_npu_dma_set_32() and
#     pnv_npu_dma_set_bypass() helpers called by it are used anywhere in the
#     kernel tree, so remove them.
#     
#     mpe: They're unused since 2d6ad41b2c21 ("powerpc/powernv: use the
#     generic iommu bypass code") removed the last usage.
