LoongArch IPI can send intterrupt to multiple CPUs, physical cpu id is
used to route interrupt for CPUs.

With cpu hotplug feature in future, logic cpu index depends on
CPUState::cpu_index heavily. Here add cpu hotplug notification interface
in IPI driver, cpu mapping logic is created inside. CPUState::cpu_index
is not used any more by IPI driver.

---
  v1 ... v2:
    1. Refresh to latest version.
    2. Rename present_cpu_map with present_map, and present_cpu with index.
    3. Replace present_cpu and cs with struct::IPICPUState.

Bibo Mao (5):
  hw/intc/loongson_ipi: Add more output parameter for cpu_by_arch_id
  hw/intc/loongarch_ipi: Add basic hotplug framework
  hw/intc/loongarch_ipi: Add cpu map table from physical cpu id
  hw/intc/loongarch_ipi: Implment cpu hotplug interface
  hw/intc/loongarch_ipi: Optimize function cpu_by_arch_id
