History
Ram Pai d862b44133 Revert "powerpc/pseries/iommu: Don't use dma_iommu_ops on secure guests" 
This reverts commit edea902c1c.

At the time the change allowed direct DMA ops for secure VMs; however
since then we switched on using SWIOTLB backed with IOMMU (direct mapping)
and to make this work, we need dma_iommu_ops which handles all cases
including TCE mapping I/O pages in the presence of an IOMMU.
