Make sure that we call the dma_unmap_sg on the correct scatterlist on
completion with the correct sg_nents.
Use sg_table to managed the DMA mapping and at the same time add the needed
dma_sync calls for the sg_table.

Oops, sorry for that.
Probably the other omap-* crypto drivers have the same issue? Can you send a
patch for them or should I do it?

With the new dma_request_chan() the client driver does not need to look for
the DMA resource and it does not need to pass filter_fn anymore.
By switching to the new API the driver can now support deferred probing
against DMA.
