[PATCH] dt-bindings: dma: xilinx: Fix "xlnx,irq-delay" type

> "xlnx,irq-delay" programs an 8-bit delay field in the DMA control
> register, and the driver stores and reads it as a byte. The binding
> described the property as a uint32 cell, which made the helper type
> check report the driver as wrong.
>
> Document "xlnx,irq-delay" as uint8 so the generated schema reflects
> the hardware field width and the existing driver access.
