cpufreq: s3cx4xx: Use generic cpufreq routines
Most of the CPUFreq drivers do similar things in .exit() and .verify() routines and .attr. So its better if we have generic routines for them which can be used by cpufreq drivers then. This patch uses these generic routines in the s3cx4xx driver. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Rafael J.
