With dtc 1.6.0, building TI device-tree files with W=2 results in warnings

/bus@100000/bus@30000000/interrupt-controller1: Missing #address-cells in
interrupt provider
Fix these by adding #address-cells = <0>; for all interrupt controllers in
TI device-tree files. Any other #address-cells value is really only needed
if interrupt-map property is being used (which is not the case for existing
TI device-tree files)

Does it really required or mandatory to have #address-cells = <0>; defined for
interrupt-controller DT nodes which
do not have child nodes and no "interrupt-map"?
