These are now used from a cpufreq driver which can be built as module,
export them.

Fixes: 86afc1df661a ("cpufreq: qcom-cpufreq-hw: Add dcvs interrupt support")
Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>

This needs to go via my ARM cpufreq tree. I will probably merge it with the
concerned commit.
