[SPARC64]: Add SG merging support back into IOMMU code.
Mimicks almost perfectly the powerpc IOMMU code, except that it doesn't have the IOMMU_PAGE_SIZE != PAGE_SIZE handling, and it also lacks the device dma mask support bits. I'll add that later as time permits, but this gets us at least back to where we were beforehand. Signed-off-by: David S. Miller <davem@davemloft.net>
