dt-bindings: dmaengine: xilinx_dma: Add xlnx,irq-delay property

Add an optional AXI DMA property 'xlnx,irq-delay'. It specifies interrupt
timeout value and causes the DMA engine to generate an interrupt after the
delay time period has expired. Timer begins counting at the end of a packet
and resets with receipt of a new packet or a timeout event occurs.

This property is useful when AXI DMA is connected to the streaming IP i.e
axiethernet where inter packet latency is critical while still taking the
benefit of interrupt coalescing.
