Yes, I agree and by "this approach" I also meant registering platform
device and waiting for its probe to happen.

Instead of adding a platform device to the reg-fixed-voltage, we can
register a regulator and thus not wait for the probe to occur.
Pushing a v2 with this change which has consistent behavior.
