By disabling cpuidle we prevent to enter to the governor computation for nothing, thus saving a lot of processing time. The only drawback is the statistic via sysfs on this state which is lost but it is meaningless and it could be retrieved from the ftrace easily.

By having a common io mapping function we can get rid of the whole table and avoid populating it for every SoC. Tested on Exynos4210, 5250 and 5420 based boards.
