Perhaps worth wrapping the dev->of_node check into the function?  I
imagine the same pattern will be quite common.

Might also make sense to warn if we've got the property but we're not
setting pm_power_off - it's indicating that things aren't working as
expected, an error will help users figure out what's going wrong.
