Revert "input: touchscreen: clean NVIDIA's derp code."

Why did I do this in the first place?

This reverts commit 4c9a47080acfa8a8de3fd5ce33bd0fb5b2163cb1.
cpufreq: interactive: remove a bunch of tunables that I don't want to use anymore as I simplified the routines. We now use up_threshold to level things out. If the load is above up_threshold then it goes straight up to max freq instead of playing around with go_hispeed_loads and what else. hispeed_freq is not even used anymore for normal routines, but its used a middle ground layer for not letting cpus to go below it during UI interaction. Also if memory serves me well its currently serving as the input boost freq. Also use the choose_freq() function (as it works together with target_load or something) for normal cpufreq operations when the load is below up_threshold.

cpufreq: interactive: choose_freq() is a bit heavier than it looked at first sight, I don't want it in a critical code PATH called a lot every second.

cpufreq: interactive: the pr_info was causing the slowdowns, and on previous commit I undone some changes by mistake. Am I drunk or what?
