Olav Haugan 64bfe1d2be iommu: Add iommu_map_sg() function 
Mapping and unmapping are more often than not in the critical path.
map_sg allows IOMMU driver implementations to optimize the process
of mapping buffers into the IOMMU page tables.

Instead of mapping a buffer one page at a time and requiring potentially
expensive TLB operations for each page, this function allows the driver
to map all pages in one go and defer TLB maintenance until after all
pages have been mapped.

Additionally, the mapping operation would be faster in general since
clients does not have to keep calling map API over and over again for
each physically contiguous chunk of memory that needs to be mapped to a
virtually contiguous region.

[mitchelh: fix existing callers and implementations of
 iommu_{map,unmap}_range to match the new function names and APIs,
 maintaining stubs for the old API so that out-of-tree modules can
 continue to compile]
