MIPS: Alchemy: devboards: sit and spin after poweroff

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

On boards which don't support poweroff, systemd complains about this fact.
In case poweroff fails, just sit and spin in the wait loop.
