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.
