dma: Add Xilinx AXI Video Direct Memory Access Engine driver support
This is the driver for the AXI Video Direct Memory Access (AXI VDMA) core, which is a soft Xilinx IP core that provides high- bandwidth direct memory access between memory and AXI4-Stream type video target peripherals. The core provides efficient two dimensional DMA operations with independent asynchronous read and write channel operation. This module works on Zynq (ARM Based SoC) and Microblaze platforms.
