LoongArch ipi can send intterrupt to multiple CPUs, physical cpu id is used to route interrupt for CPUs.
With cpu hotplug feature in future, notification for ipi interrupt controller is required. Here cpu hotplug interface is added on ipi class, so that gpio irq line is connected to cpu irq line, and irq routing can be setup.
