PM / OPP: Don't create debugfs "supply-0" directory unnecessarily

Browse Source 
We create "supply-0" debugfs directory even if the device doesn't do
voltage scaling. That looks confusing, as if the regulator is found but
we never managed to get voltage levels for it.

Avoid creating such a directory unnecessarily.
