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

["Rob Herring (Arm)" <robh@kernel.org>]

"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.
