6.6-stable review patch. If anyone has any objections, please let me know.

From: Konrad Dybcio konrad.dybcio@linaro.org
[ Upstream commit ad6556fb45d4ab91ad786a2025cbe2b0f2e6cf77 ]
The idle state entry/exit/residency times differ from what shipped on production devices, mostly being overly optimistic in entry times and overly pessimistic in minimal residency times. Align them with downstream sources.
