From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Because the number of trip points in each thermal zone and their
types are known to intel_soc_dts_iosf_init() prior to the registration
of the thermal zones, make it create an array of struct thermal_trip
entries in each struct intel_soc_dts_sensor_entry object and make
add_dts_thermal_zone() use thermal_zone_device_register_with_trips()
for thermal zone registration and pass that array as its second
argument.

Drop the sys_get_trip_temp() and sys_get_trip_type() callback
functions along with the respective callback pointers in
tzone_ops, because they are not necessary any more.
