Fix this by adding the missing "maxItems". As the architectural maximum is 4095 interrupts, using that as the limit would be unpractical. Hence limit it to 10 interrupts (two interrupts for a system management core, and two interrupts per core for other cores). This should be sufficient for now, and the limit can always be increased when the need arises.
