It is reported that commit 95021088 ("thermal: core: Drop trips_disabled bitmask") causes the maximum frequency of CPUs to drop further down with every system sleep-wake cycle on Intel Core i7-4710HQ. This turns out to be due to a trip point whose temperature is equal to 0 degrees Celsius which is acted on every time the system wakes from sleep. Before commit 95021088 this trip point would be disabled wia the trips_disabled bitmask, but now it is treated as a valid one. Since ACPI thermal control is generally about protection against overheating, trip points with temperature of 0 centigrade or below are not particularly useful there, so initialize them all as invalid which fixes the problem at hand.
