[PATCH 05/11] reboot: indicate whether it is a HARDWARE PROTECTION reboot or shutdown

It currently depends on the caller, whether we attempt a hardware
protection shutdown (poweroff) or a reboot. A follow-up commit will make
this partially user-configurable, so it's a good idea to have the
emergency message clearly state whether the kernel is going for a reboot
or a shutdown.
