So here the regulator core knows that there is no regulator and never

There may be some side effects if we just return ERR_PTR(-ENODEV) when
regulator_dev_lookup returns -ENODEV. Maybe Mark has some comments to
this.

I'm concerned about how this is going to interact with all the plans
people have for dynamically loading device tree fragments during
enumeration.
