hw/loongarch/virt: Modify ipi as percpu device
ipi is used to communicate between cpus, this patch modified loongarch ipi device as percpu device, so that there are 2 MemoryRegions with ipi device, rather than 2*cpus MemoryRegions, which may be large than QDEV_MAX_MMIO if more cpus are added on loongarch virt machine.
