cpufreq: Introduce CPUFREQ_GOV_STRICT_TARGET
Introduce a new governor flag, CPUFREQ_GOV_STRICT_TARGET, for the governors that want the target frequency to be set exactly to the given value without leaving any room for adjustments on the hardware side and set this flag for the powersave and performance governors.
