With the current configuration, a CPU cooling device is the cpufreq cooling device. As we want to add a new CPU cooling device, let's convert the CPU cooling to a choice giving a list of CPU cooling devices. At this point, there is obviously only one CPU cooling device. There is no functional changes.
