[4.4.y-cip 04/15] PM / OPP: Remove 'operating-points-names' binding


Chen-Yu Tsai (Moxa) <wens@...>
 

From: Viresh Kumar <viresh.kumar@linaro.org>

commit af87a39a5f7cf6ef252b1aec3e2e6508a40e51f1 upstream.

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.
