Instead of global qemu_system_powerdown we could use notifiers like it's done
for suspend, I'll post patches today after testing them on target-i386.

BTW getting rid of qemu_system_powerdown is orthogonal to topic of this series.
I hope you won't object to this patch providing there will be follow on series
to deal with qemu_system_powerdown.
