DMA-API.txt: remove dma_sync_single_range description
dma_sync_single_for_cpu/for_device supports a partial sync so there is no point to have dma_sync_single_range (also dma_sync_single was obsoleted long ago, replaced with dma_sync_single_for_cpu/for_device). There is no user of dma_sync_single_range() in mainline and only Alpha architecture supports dma_sync_single_range(). So it's unlikely that someone out of the tree uses it.

535Does a partial sync, starting at offset and continuing for size. You
536must be careful to observe the cache alignment and width when doing
537anything like this. You must also be extra careful about accessing
538memory you intend to sync partially.
