LoongArch extioi interrupt controller routes peripheral interrupt
to multiple CPUs, physical cpu id is used in interrupt routing table.
Here hotplug interface is added for extioi object, so that parent irq
line can be connected, and routing table can be added for new created
cpu.
Here only basic hotplug framework is added, it is stub function.

When cpu is added, it will connect gpio irq line to cpu irq.
And cpu hot-add is put in common code, move gpio irq initial
part into common code.

Since cpu number can be acquired from possible_cpu_arch_ids(),
num-cpu property is not necessary. Here remove num-cpu property
for object TYPE_LOONGARCH_EXTIOI_COMMON object.
