You are right. The SDHCI driver should work just fine without
implementing pre_req and post_req but you wont see any performance
increasing for DMA usage.
In order to benefit from the patchset you need to implement pre_req
and post_req.

If you run into trouble implementing those hooks or if you have any
questions please let me know.
