Add arch_unregister_cpu() to allow the ACPI machinery to call
unregister_cpu(). This is enough for arm64, riscv and loongarch, but
needs to be overridden by x86 and ia64 who need to do more work.

An open question remains from the RFC v2 posting: should we provide a
__weak stub for !HOTPLUG_CPU as well, since in later patches ACPI may
reference this if the compiler doesn't optimise as we expect?
Changes since v1:
* Added CONFIG_HOTPLUG_CPU ifdeffery around unregister_cpu
Changes since RFC v2:
* Move earlier in the series
