Patch for adding map_sg/unmap_sg to the generic IOMMU API.
v3 -> v4:
* Removed BUG_ON in both map_sg and unmap_sg
* Removed PAGE_ALIGN of length of mapping
v2 -> v3:
* Updated commit text
* Simplifed fallback code and fixed variable types in map_sg function.
* Renamed and changed arguments to map and unmap functions
v1 -> v2:
* Added support for "option" argument to unmap call. This can be used by
IOMMU driver implentations to allow clients to signal to the driver not
to do TLB invalidate for example.
* Added fallback in case iommu_{map,unmap}_range is called for an IOMMU driver
that does not have these implemented.
* Rebased on top of Joerg's tree.
* Split out patch from the rest of the patches.
