POWERPC: Set dma_data correctly for direct_ops on pasemi
More late-caught fallout from the mainline merge. Commit
35e4a6e26d0c6bc7f32087db61f0fb3666531183 ("[POWERPC] Use
archdata.dma_data in dma_direct_ops and add the offset") claimed
"Now that all platforms using dma_direct_offset setup the
archdata.dma_data correctly, ..."
..but nope -- the pasemi iommu setup code that disables translation on
the DMA pci device didn't set dma_data correctly.
This fixes it.
