[RESEND][PATCH v1 3/8] thermal: qcom: Use thermal_zone_get_crit_temp() in qpnp_tm_init()

[Rafael J. Wysocki]

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 a struct thermal_trip pointer
from a trip index until it finds the critical one.
