thermal/drivers/Kconfig: Convert the CPU cooling device to a choice
The next changes will add a new way to cool down a CPU by injecting idle cycles. 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.

This implements the generic cpu cooling mechanism through frequency
reduction. An ACPI version of this already exists
(drivers/acpi/processor_thermal.c).
This will be useful for platforms using the generic thermal interface
and not the ACPI interface.
- If you want this support, you should say Y here.
