ACPI: thermal: Introduce struct acpi_thermal_trip
Add struct acpi_thermal_trip to contain the temperature and valid flag of each trip point in the driver's local data structures. This helps to make the subsequent changes more straightforward. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
