 [PATCH v1 07/10] thermal: core: Relocate functions that update trip points

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

In preparation for subsequent changes, move two functions used
for updating trip points, thermal_zone_set_trip_temp() and
thermal_zone_set_trip_hyst(), to thermal_core.c.

No functional impact.
