cpufreq: governor: Add a ->start callback for governors
To avoid having to check the governor type explicitly in the common code in order to initialize data structures specific to the governor type properly, add a ->start callback to struct dbs_governor and use it to initialize those data structures for the ondemand and conservative governors.
