"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.
