Missing description. + add "microblaze: " prefix to subject.

I have looked at the patch again and I would prefer
to separate it to 3 patches.

1. Move __dma_sync to dma-mapping.h + fix parameters.
2. Introduce new sync operations
3. The rest of changes in dma code.

I have no problem to apply patch 1 and 2.
If you show me bug you see with patch 3, I will test it and keep in my repo for a while.
As I wrote in my previous post, I am open to add your comment to dma code
that flush will be safer to use but slower if cache lines are dirty but I don't like
to cache the code without real problem.
In any case, if you show me, on program/driver/etc that the problem is in invalidation
I will apply it without no problem.

Thanks for your patches,

Michal Simek, Ing. (M.Eng)
