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.

+Required properties:
+- compatible: Must be "regulator";

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

+- mode-fast: boolean, Can handle fast changes in its load
+- mode-normal: boolean, Normal regulator power supply mode
+- mode-idle: boolean, Can be more efficient during light loads
+- mode-standby: boolean, Can be most efficient during light loads

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

+- apply-uV: apply uV constraint if min == max

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