This reverts commit 13d1c44fbb08fc78931e54b53dfc29d946805b47.
cpufreq: interactive: Support variable frequency calculations

Use a threshold value up to which we are evaluating the current
speed weighted by current load against each new choice of speed.
Above switch to the original frequency calculation proportional to
load relative to the max possible frequency which allows for more
dynamic and fair changes.

Default threshold is policy min which guarantees minimal freqs
and energy usage during (offloaded) media playback.
