From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
Modify qpnp_tm_init() to use thermal_zone_get_crit_temp() to get the
critical trip temperature instead of iterating over trip indices and
using thermal_zone_get_trip() to get from a trip index to struct
thermal_trip until it finds the critical one.
