a bunch of changes

Changed highest frequency back to 1.624GHz and core voltage back to
1200mV.

Refresh rate now adjusted with GPU OC clock at compile time. Higher FPS
should be realized at 484 and 520 for most (thanks to clemsyn for
sharing his research and findings)

Adjustments to the tegra 3 algorirthim for bring cpus online and
offline, especially for the OC frequencies.

Fixed GPU clock compile time switch. Removed 500MHz choice.

Moved the frequency policy to 1.3GHz on startup to cpu 0 only.

Minor adjustment to the interactive governor to make it slightly more
responsive when demand increases.
