cpuidle: governors: teo: Refine tick_intercepts vs total events check

Browse Source 
Use 2/3 as the proportion coefficient in the check comparing
cpu_data->tick_intercepts with cpu_data->total because it is close
enough to the current one (5/8) and it allows of more straightforward
interpretation (on average, intercepts within the tick period length
are twice as frequent as other events).
