[PATCH v1 04/13] ACPI: thermal: Merge trip initialization functions

[Rafael J. Wysocki]

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

In order to reduce code duplicationeve further, merge
acpi_thermal_init_passive/active_trip() into one function called
acpi_thermal_init_trip() that will be used for initializing both
the passive and active trip points.

No intentional functional impact.
