Devendra K Verma bda8e00b35 dmaengine: dw-edma: Set status for callback_result 
[ Upstream commit 5e742de97c ]

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.
