cpufreq: Convert printk(KERN_<LEVEL> to pr_<level>
Use the more common logging style. Miscellanea: o Coalesce formats o Realign arguments o Add a missing space between a coalesced format Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
