checks: Check the overall length of "interrupt-map" 

It is possible the overall length of "interrupt-map" is shorter than
expected. A likely scenario is if "#address-cells" in the interrupt
parent is not accounted for and there is only a single map entry. With
multiple entries, one of the other tests would likely fail.
