Don't go hiding the bindings for things away from the code they're
binding.  Bindings for the regualtor API are a regulator API thing and
should be part of the regulator API code.

Is this idiomatic or should we just have a helper that parses a big list
of properties from the device node?

I guess these are actually permissions to set the given modes?  The
documentation should be clearer.

This seems a bit Linux/runtime policy specific (especially the last
bit).
