thermal: cpu_cooling: remove unnecessary wrapper get_cpu_frequency()
get_cpu_frequency() isn't doing much by itself, just calling get_property(). And so this wrapper isn't required at all. Get rid of it. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
