Rafael J. Wysocki 16c8d7586c cpuidle: teo: Skip sleep length computation for low latency constraints ...

If the idle state exit latency constraint is sufficiently low, it
is better to avoid the additional latency related to calling
tick_nohz_get_sleep_length().  It is also not necessary to compute
the sleep length in that case because shallow idle state selection
will be forced then regardless of the recent wakeup history.

Accordingly, skip the sleep length computation and subsequent
checks of the exit latency constraint is low enough.
