Subject: [RFC PATCH v3 5/7] dt-bindings: regulator: bd9576 add FET
 ON-resistance for OCW

BD9576MUF provides over-current protection and detection. Current is
measured as voltage loss over external FET. Allow specifying FET's on
resistance so current monitoring limits can be converted to voltages.
