[SPARC64]: Eliminate PCI IOMMU dma mapping size limit.
The hairy fast allocator in the sparc64 PCI IOMMU code has a hard limit of 256 pages. Certain devices can exceed this when performing very large I/Os. So replace with a more simple allocator, based largely upon the arch/ppc64/kernel/iommu.c code. Signed-off-by: David S. Miller <davem@davemloft.net>
