The property is correct AFAICT, we have:

                        interrupts-extended = <&irq0_aon_intc 0x6>,
                                              <&aon_pm_l2_intc 0x5>;

with both interrupt controllers having #interrupt-cells = <1>. I tried
documenting the interrupts-extended for brcm,brcmstb-gpio.yaml to have
maxItems: 2 but that does not eliminate the warning. Do you have any
suggestions?
