Subject: [PATCH 1/5] dt-bindings: dmaengine: xilinx_dma: Add xlnx,axistream-connected property

From: Radhey Shyam Pandey <radhey.shyam.pandey@...inx.com>

Add an optional 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.
