[PATCH v2 4/4] irqchip: sifive-plic: Implement irq_set_affinity() for SMP host

Currently on SMP host, all CPUs take external interrupts routed via PLIC. All CPUs will try to claim a given external interrupt but only one of them will succeed while other CPUs would simply resume whatever they were doing before. This means if we have N CPUs then for every external interrupt N-1
