cpuidle: menu: fixed wrapping timers at 4.294 seconds
commit 7467571f4480b273007517b26297c07154c73924 upstream.
Cpuidle menu governor is using u32 as a temporary datatype for storing
nanosecond values which wrap around at 4.294 seconds. This causes errors
in predicted sleep times resulting in higher than should be C state
selection and increased power consumption. This also breaks cpuidle
state residency statistics.
