iommu: generalize the batched sync after map interface
For the upcoming IOVA-based DMA API we want to batch the
ops->iotlb_sync_map() call after mapping multiple IOVAs from
dma-iommu without having a scatterlist. Improve the API.
Add a wrapper for the map_sync as iommu_sync_map() so that callers
don't need to poke into the methods directly.
Formalize __iommu_map() into iommu_map_nosync() which requires the
caller to call iommu_sync_map() after all maps are completed.
Refactor the existing sanity checks from all the different layers
into iommu_map_nosync().
