stable: commit "cpuidle: menu: Avoid discarding useful information" causes regressions

[Sergey Senozhatsky]

Hello,

We are observing performance regressions (cpu usage, power
consumption, dropped frames in video playback test, etc.)
after updating to recent stable kernels.  We tracked it down
to commit 3cd2aa93674e in linux-6.1.y and commit 3cd2aa93674
in linux-6.6.y ("cpuidle: menu: Avoid discarding useful information",
upstream commit 85975daeaa4).

Upstream fixup fa3fa55de0d ("cpuidle: governors: menu: Avoid using
invalid recent intervals data") doesn't address the problems we are
observing.  Revert seems to be bringing performance metrics back to
pre-regression levels.
