iommu sg: powerpc: convert iommu to use the IOMMU helper
This patch converts PPC's IOMMU to use the IOMMU helper functions. The IOMMU doesn't allocate a memory area spanning LLD's segment boundary anymore. iseries_hv_alloc and iseries_hv_map don't have proper device struct. 4GB boundary is used for them.
