Recently you've made a conversion to YAML for arm,pl17x memory controllers
and now this warning is reported - and by the way I believe and it's
opposite to the commit message, the warning is not reported in the upstream,
because lpc3250-ea3250.dts does not enable the controller.

I wonder and let me ask you, why two address cells are needed here?

My default preference is to get one address cell for NOR flash ICs, and
I'd suggest to make a change to the dt binding of the controller.
