On certain cases we have seen usleep_range() return before
the intended minimum time parameter passed to this function.
There is no protection against wakeups and we may return
early. msleep() already has code to handle this cases since
it loops as long as there is still time.

TSENS (temperature sensor) controller provides capability
to program the gain and offset for individual sensors so that
the controller reports the temperature. The efuse information
for gain and offset can be read during boot and programmed
at boot initialization and the application TSENS driver
does not need to support reading from the efuse region.
Update the property for reading the tsens efuse as optional
for such cases.

The handle_critical_trips() api in thermal_core gets
invoked during the system resume path on 4.4 kernel.
If a thermal driver has registered for the critical trip
zone the handle_critical_trips() reads the current temperature
and checks against the critical threshold. If the
temperature value is greater than the critical threshold
the device is shutdown.
Remove registering the critical trip zone since its not
used by thermal sys clients. The driver will continue
to use it internally to set thresholds and monitor
the state of the TSENS (temperature sensor) controller.
