PM / Sleep: Add "prevent autosleep time" statistics to wakeup sources
Android uses one wakelock statistics that is only necessary for opportunistic sleep. Namely, the prevent_suspend_time field accumulates the total time the given wakelock has been locked while "automatic suspend" was enabled. Add an analogous field, prevent_sleep_time, to wakeup sources and make it behave in a similar way. Signed-off-by: Rafael J.
