Add a check for parsing 'interrupt-map' properties. The check primarily
tests parsing 'interrupt-map' properties which depends on and the parent
interrupt controller (or another map) node.
Note that this does not require '#address-cells' in the interrupt-map
parent, but treats missing '#address-cells' as 0 which is how the Linux
kernel parses it. There's numerous cases that expect this behavior.
