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.

Bibo Mao (3):
  hw/intc/loongarch_ipi: Add basic hotplug framework
  hw/intc/loongarch_ipi: Implment cpu hotplug interface
  hw/intc/loongarch_ipi: Notify ipi object when cpu is plugged
