[PATCH v2 7/8] thermal: trip: Get rid of thermal_zone_get_num_trips()

["Rafael J. Wysocki" <rjw@rjwysocki.net>]

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

The only existing caller of thermal_zone_get_num_trips(), which is
rcar_gen3_thermal_probe(), uses this function to put the number of
trip points into a kernel log message, but this information is also
available from the thermal sysfs interface.

For this reason, remove the thermal_zone_get_num_trips() call from
rcar_gen3_thermal_probe() and drop the former altogether.

A new version, based on the discussion following the v1:

https://lore.kernel.org/linux-pm/20240617183949.GO382677@ragnatech.se/

The Renesas driver change does not depend on the previous patches
in the series.
