This isn't really a regulator specific thing - it's common for the
actual implementation to be to simply cut power but it could be
something that doesn't look like a regulator doing it like a system
monitor.  I'd rename this to something like is_system_poweroff_source().

You probably also want to CC the DT maintainers on this and add some
documentation of this as a standard property, not entirely sure where
exactly but I'm sure the DT people could advise.
