hw/loongarch/virt: Modify ipi as percpu device

Browse source 
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.
