cpufreq: governor: Create generic macro for common tunables
Some tunables are present in governor-specific structures, whereas one (min_sampling_rate) is located directly in struct dbs_data. There is a special macro for creating its sysfs attribute and the show/store callbacks, but since more tunables are going to be moved to struct dbs_data, a new generic macro for such cases will be useful, so add it and use it for min_sampling_rate.
