[PATCH v2] Add Xilinx AXI Video DMA Engine driver

[Srikanth Thokala]

Hi,

This is the driver for Xilinx AXI Video Direct Memory Access Engine.
It is a soft IP core, which provides high-bandwidth direct memory
access between memory and AXI4-Stream video type target peripherals
including peripherals which support AXI4-Stream Video Protocol. The
core provides efficient two dimensional DMA operations with independent
asynchronous read and write channel operation.

For more information on the IP, please refer to

Use cases:

1. Xilinx Video Targeted Reference design
