thermal/debugfs: Use helper to update trip point overstepping duration

Browse Source 
Add a helper for updating trip point overstepping duration to be called
from thermal_debug_tz_trip_down().

Subsequently, it will also be used during resume from system-wide
suspend.

No intentional functional impact.
