[RFC v2 PATCH 1/7] dt-bindings: dmaengine: xilinx_dma: Add xlnx,axistream-connected property

[Radhey Shyam Pandey]

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.

Changes for v2:
- Rename xlnx,axieth-connected to xlnx,axistream-connected to
  make it generic.
