powerpc/dma: Add struct iommu_table argument to iommu_map_sg()

Make iommu_map_sg take a struct iommu_table. It did so before commit
740c3ce66700640a6e6136ff679b067e92125794 (iommu sg merging: ppc: make
iommu respect the segment size limits).

This stops the function looking in the archdata.dma_data for the iommu
table because in the future it will be called with a device that has
no table there.

This also has the nice side effect of making iommu_map_sg() match the
other map functions.
