AXI DMA support is added to the existing AXI VDMA driver.
The binding doc for AXI DMA should also be updated in the
VDMA device-tree binding doc.

-Xilinx AXI DMA engine, it does transfers between memory and AXI4 stream
-target devices. It can be configured to have one channel or two channels.
-If configured as two channels, one is to transmit to the device and another
-is to receive from the device.
-
-Required properties:
-- compatible: Should be "xlnx,axi-dma-1.00.a"
-- #dma-cells: Should be <1>, see "dmas" property below
-- reg: Should contain DMA registers location and length.
-- dma-channel child node: Should have atleast one channel and can have upto
- two channels per device. This node specifies the properties of each
- DMA channel (see child node properties below).
-
-Optional properties:
-- xlnx,include-sg: Tells whether configured for Scatter-mode in
- the hardware.
-
-Required child node properties:
-- compatible: It should be either "xlnx,axi-dma-mm2s-channel" or
- "xlnx,axi-dma-s2mm-channel".
-- interrupts: Should contain per channel DMA interrupts.
-- xlnx,datawidth: Should contain the stream data width, take values
- {32,64...1024}.
-
-Option child node properties:
-- xlnx,include-dre: Tells whether hardware is configured for Data
- Realignment Engine.
-
-Example:
-++++++++
-
-axi_dma_0: axidma@40400000 {
- compatible = "xlnx,axi-dma-1.00.a";
- #dma_cells = <1>;
- reg = < 0x40400000 0x10000 >;
- dma-channel@40400000 {
- compatible = "xlnx,axi-dma-mm2s-channel";
- interrupts = < 0 59 4 >;
- xlnx,datawidth = <0x40>;
- } ;
- dma-channel@40400030 {
- compatible = "xlnx,axi-dma-s2mm-channel";
- interrupts = < 0 58 4 >;
- xlnx,datawidth = <0x40>;
- } ;
-} ;

-* DMA client
-
-Required properties:
-- dmas: a list of <[DMA device phandle] [Channel ID]> pairs,
- where Channel ID is '0' for write/tx and '1' for read/rx
- channel.
-- dma-names: a list of DMA channel names, one per "dmas" entry
-
-Example:
-++++++++
-
-dmatest_0: dmatest@0 {
- compatible ="xlnx,axi-dma-test-1.00.a";
- dmas = <&axi_dma_0 0
- &axi_dma_0 1>;
- dma-names = "dma0", "dma1";
