opp: Allow _generic_set_opp_clk_only() to work for non-freq devices
In order to avoid conditional statements at the caller site, this patch updates _generic_set_opp_clk_only() to work for devices that don't change frequency (like power domains, etc.). Return 0 if the clk pointer passed to this routine is not valid. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Tested-by: Dmitry Osipenko <digetx@gmail.com>
