dt-bindings/bcm283x: Define polarity of per-cpu interrupts

This patch define the polarity of the per-cpu interrupts on BCM2836 and BCM2837 in order to avoid the warnings from ARM arch timer code: arch_timer: WARNING: Invalid trigger for IRQ19, assuming level low arch_timer: WARNING: Please fix your firmware arch_timer: cp15 timer(s) running at 19.20MHz (virt).
