[PATCH V11 5/7] soc: qcom: rpmpd: Add support for set performance state

[Viresh Kumar]

From: Rajendra Nayak <rna...@codeaurora.org>

NOT FOR MERGE.

With genpd now expecting power domain drivers supporting performance
state to support set performance state callbacks, add support for it in
the rpmpd driver.
