dmaengine: dw-edma: Set status for callback_result

DMA Engine has support for the callback_result which provides
the status of the request and the residue. This helps in
determining the correct status of the request and in
efficient resource management of the request.
The 'callback_result' method is preferred over the deprecated
'callback' method.
