[PATCH 1/8] cpufreq: allow drivers to flag custom support for freq invariance

The scheduler's Frequency Invariance Engine (FIE) is providing a frequency scale correction factor that helps achieve more accurate load-tracking by conveying information about the currently selected frequency relative to the maximum supported frequency of a CPU. In some cases this is achieved by
