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.
