Some background about the patch series: Xilinx Axi Ethernet device driver
(xilinx_axienet_main.c) currently has axi-dma code inside it. The goal is
to refactor axiethernet driver and use existing AXI DMA driver using
DMAEngine API.

This patchset does feature addition and optimization to support axidma
integration with axiethernet network driver. Once axidma version is
accepted mcdma specific changes will be added in followup version.

Changes in V2: 
1) Moved xlnx,axistream-connected optional property to under AXI DMA.
2) Removed Acked-by: Rob Herringi for PATCH 1/6.
3) New patch(6/6).
 
Comments, suggestions are very welcome!
