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

BTW I just notice that this values specification is ambiguous as to
whether 96 is a valid value or only powers of 2 like 128. Maybe you want
to clarify that in a follow-up patch?

It should be only power of 2.  I could send a patch, but it is design-specific and
the design will not allow to take the intermediate values and so the device-tree

Thanks for this patch.
