A processing element should never return from a wfi, however, due to a
hardware bug, certain CPUs may wake up because of an external event.
This patch tightens the behaviour of the common power down sequence, it
ensures the routine never returns by entering a wfi loop at its end. It
aligns with the behaviour of the platform implementations.
