dt-bindings: dmaengine: xilinx_dma:Add xlnx,axistream-connected property
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.
