[PATCH v1 3/6] thermal: intel: int340x: Evaluate GTSH once

[Rafael J. Wysocki]

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

It is not necessary to evaluate the GTSH ACPI object for every trip
point in int340x_thermal_zone_add() and the function used for that
is not really necessary either, because it only has one caller.

Accordingly, fold the evaluation of GTSH directly into
int340x_thermal_zone_add(), evaluate it only once and populate the
hysteresis for all of the trip points with the value produced by it.

No expected functional impact.
