#1259158 — [PATCH 3/3] PM / OPP: Remove 'operating-points-names' binding

These aren't used until now by any DT files and wouldn't be used now as
we have a better scheme in place now, i.e. opp-property-<name>
properties.

Remove the (useless) binding without breaking ABI.

-Devices may want to choose OPP tables at runtime and so can provide a list of

 If required, this can be extended for SoC vendor specfic bindings. Such bindings
 should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
