dmaengine: xilinx_dma: Pass AXI4-Stream control words to dma client

Browse source

Read DT property to check if AXI DMA is connected to streaming IP
i.e axiethernet. If connected i.e xlnx,axistream-connected property
is present in the dma node then pass AXI4-Stream control words to dma
client using metadata_ops dmaengine API.

If not connected then driver won't support metadata_ops dmaengine API
and continue to support all legacy usecases.
