With the new dma_request_chan() the clinet 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 davinci_mmc driver can now support deferred
probing against DMA.

Provide the dma_filter_map to edma which will allow us to move the drivers
to the new, simpler dmaengine API and we can remove the DMA resources also
for the devices.

In order to switch the driver to use the new simpler dmaengine API the
device mapping for the dma instances needs to be added and also the DMA
resources should be named.
