mach-tegra: cpu: several changes, see commit msg

* fix max cpufreq reset throughout the kernel.
* allow 1600mhz cpuoc (dvfs/edp)
* all cores clock with set max
* ignore variants (everyone can oc to 1.6Ghz)
* raise max default max clock to 1.3Ghz (=all cores, so in the worst case scenario we are 4x100Mhz overclocked)
* ondemand touchpoke modification to respect set max limits
* earlysuspend/lateresume to limit/unlimit our cpu to 475Mhz/set max freq on screen off/on
