[PATCH RESEND] Documentation: devicetree: Fix Xilinx VDMA specification

["Andreas Färber" <afaerber-l3A5Bk7waGM@public.gmane.org>]

The specification requires xlnx,data-width, but example and driver use
xlnx,datawidth. Change the specification to match the implementation.

Reviewed-by: Michal Simek <michal.simek-gjFFaj9aHVfQT0dZR+AlfA@public.gmane.org>
Fixes: eebeac03db93 ("dma: Add Xilinx Video DMA DT Binding Documentation")
