cpuidle: sysfs: Add per cpu idle state prediction statistics
This patch gives some statitics under /sys/devices/system/cpu/cpuX/cpuidle/stats
The statistics are regarding the prediction vs the idle state.
under_estimate: the sleep duration was longer than expected and a deeper idle
could have been choose in this case
over_estimate: the sleep duration was shorter than expected and we should have
chose a shallower state, that increase exit latency
right_estimate: the sleep duration is correct regarding the target residency
and the idle state chose.
