drivers: thermal: Force notify thermal to re-evaluate TSENS sensors

If TSENS controller went to bad state while reading temperature
of a sensor, TSENS invokes controller re-init code for all
controller and then notifies the thermal framework to
re-evaluate thermal for each sensor.But there is a chance that
current notification API can bail out without re-evaluating the
thermal zone if none of the trips are violated.

Notify the thermal framework with proper notification API to force
re-evaluate thermal zone and make sure that all sensors are re-enabled
next active trips.
