As the DT bindings lack an upper bound on the number of interrupts, thus assuming one, proper grouping is currently flagged as an error. Fix this by adding the missing "maxItems", limiting it to 9 interrupts (one interrupt for a system management core, and two interrupts per core for other cores), which should be sufficient for now. Group the tuples in the example.
