From: Radhey Shyam Pandey <radhey.shyam.pandey@xxxxxxxxxx>
Add an optional AXI DMA property 'xlnx,axistream-connected'. This
can be specified to indicate that DMA is connected to a streaming IP
in the hardware design and dma driver needs to do some additional
handling i.e pass metadata and perform streaming IP specific
configuration.
