Christian Loehle 4499143980 cpuidle: teo: Remove recent intercepts metric ... The logic for recent intercepts didn't work, there is an underflow of the 'recent' value that can be observed during boot already, which teo usually doesn't recover from, making the entire logic pointless. Furthermore the recent intercepts also were never reset, thus not actually being very 'recent'. Having underflowed 'recent' values lead to teo always acting as if we were in a scenario were expected sleep length based on timers is too high and it therefore unnecessarily selecting shallower states. Experiments show that the remaining 'intercept' logic is enough to quickly react to scenarios in which teo cannot rely on the timer expected sleep length.
