ACPI CPU hotplug related initialization should only happend if ACPI_CPU_HOTPLUG
support has been enabled for particular architecture. Add cpu_hotplug_hw_init()
stub to avoid compilation break.

Already dealt. Now, part of architecture agnostic patch-set,

https://lore.kernel.org/qemu-devel/4764CF47-47CA-4685-805C-BBE6310BE164@oracle.com/T/#m8d14dedab8dbd9fdc66324ff013b9b9966569813


Thanks
