[PATCH] dmaengine: vdma: Add support for cyclic dma mode

This patch adds support for AXI DMA cyclic dma mode. In cyclic mode, DMA fetches and processes the same BDs without interruption. The DMA continues to fetch and process until it is stopped or reset. Signed-off-by: Kedareswara rao Appana --- drivers/dma/xilinx/xilinx_vdma.c | 179
