Added Omegamoon's CPU gov. and IO sched.

Optional extra I/O schedulers:
- Simple IO scheduler
- V(R) IO scheduler

Optional CPU freq. governors:
- smartassV2
- savagedzen
- interactiveX
WARNING: very important function rk3188_get_temp is hardcoded!

Found this function that has been hardcoded as 60 degrees.
TODO: find out if it's really used to adjust cpu freq and if there are any means to find rk3188's temperature
Minor comment on missing GPIO5 for RK3066
