Dmitry Osipenko 1d7ae53b15 iommu: Introduce iotlb_sync_map callback
Introduce iotlb_sync_map() callback that is invoked in the end of
iommu_map(). This new callback allows IOMMU drivers to avoid syncing
after mapping of each contiguous chunk and sync only when the whole
mapping is completed, optimizing performance of the mapping operation.
