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.
