powerpc/iommu: Use coherent_dma_mask for alloc_coherent
The IOMMU code has been passing the dma-mask instead of the
coherent_dma_mask to the iommu allocator. Coherent allocations should
be made using the coherent_dma_mask.
Also update the vio code to ensure the coherent_dma_mask is set. Without
this change drivers, such as ibmvscsi, fail to load with the corrected
dma_iommu_alloc_coherent().
