An interrupt provider (an actual interrupt-controller node or an
interrupt nexus) should have both #address-cells and #interrupt-cells
properties explicitly defined.
Add an extra test for this. We check for the #interrupt-cells property
already, but this does not cover every controller so far, only those that
get referenced by an interrupts property in some node. Also we miss
interrupt nexus nodes.
A missing #address-cells property is less critical, but creates
ambiguities when used in interrupt-map properties, so warn about this as
well now.
This removes the now redundant warning in the existing interrupts test.
