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.
