target/arm: Move start-powered-off property to generic CPUState
There are other platforms which also have CPUs that start powered off, so
generalize the start-powered-off property so that it can be used by them.
Note that ARMv7MState also has a property of the same name but this patch
doesn't change it because that class isn't a subclass of CPUState so it
wouldn't be a trivial change.
This change should not cause any change in behavior.
