cpufreq: governor: Rename some data types and variables
The ondemand and conservative governors are represented by struct common_dbs_data whose name doesn't reflect the purpose it is used for, so rename it to struct dbs_governor and rename variables of that type accordingly. No functional changes. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
