MIPS: Fix poweroff failure when HOTPLUG_CPU configured.
commit 8add1ecb81f541ef2fcb0b85a5470ad9ecfb4a84 upstream.
When poweroff machine, kernel_power_off() call disable_nonboot_cpus().
And if we have HOTPLUG_CPU configured, disable_nonboot_cpus() is not an
empty function but attempt to actually disable the nonboot cpus. Since
system state is SYSTEM_POWER_OFF, play_dead() won't be called and thus
disable_nonboot_cpus() hangs. Therefore, we make this patch to avoid
poweroff failure.
