[PATCH] powerpc/pseries/iommu: update outdated comment for renamed iommu_dev_setup_pSeries()

[Kexin Sun]

The function iommu_dev_setup_pSeries() was renamed to
pci_dma_dev_setup_pSeries() by commit 12d04eef927b
("[POWERPC] Refactor 64 bits DMA operations").  Update
the stale reference in pci_dma_bus_setup_pSeries().
