mlx4: replace the dma_sync_single_range_for_cpu/device API 

There are only two users of the dma_sync_single_range_for_cpu/device
API in mainline (mlx4 and ssb). The
dma_sync_single_range_for_cpu/device API has never been documented and
the dma_sync_single_for_cpu/device API also support a partial sync.

This converts mlx4 to use the dma_sync_single_for_cpu/device API
(preparations for the removal of the dma_sync_single_range_for_cpu/device API).
