Add a new function iommu_context_addr() which takes care of the differences and returns a pointer to a context entry which may be in either format. The formats are binary compatible for all the old fields anyway; the new one is just larger and some of the reserved bits in the original 128 are now meaningful. So far, nothing actually uses the new fields in the extended context entry. Modulo hardware bugs with interpreting the new-style tables, this should basically be a no-op. Signed-off-by:
