The only time this code gets called outside of the normal power on/off
path is regulator_force_disable(). And the enable event is only called
inside regulator_enable() which would already be part of the normal
power up path.

I still don't see the need for this code at all, I do not want to fix
unused broken code, and if no one else will fix it, the code should be
dropped.
