Subject: [PATCH -mm 3/4] alpha: remove dma_sync_single_range

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.
