Subject: [PATCH v6 06/19] PM / devfreq: tegra30: Tune up boosting thresholds

Now that average-sustain coefficient / multiplier is gone, it won't hurt
to re-tune the boosting thresholds to get a bit harder boosting for MCALL
clients, resulting in a more reactive governing in a case of multimedia
applications usage like 3d / video.
