Fixes and worthwhile governors

Moved to SLUB because http://forum.xda-developers.com/nexus-s/general/ref-memory-allocator-benchmark-t1696284 and it fixes the frequency lock. Enabled RCU priority boosting because it works.

Added Abyssplug and Wheatley because they are worthwhile to have on Tegra3 platforms (i haven't tested Abyssplug extensively yet but Wheatley is nice).

Added Westwood congestion algorithm because it works well on mobile data/wireless.

Fixed the compile errors resulting from ntemis changes to tegra-camera.
