thermal/drivers/cpuidle_cooling: Change the registration function

Today, there is no user for the cpuidle cooling device. The targetted platform is ARM and ARM64. The cpuidle and the cpufreq cooling device are based on the device tree. As the cpuidle cooling device can have its own configuration depending on the platform and the available idle states. The DT node description will give the optional properties to set the cooling device up. Do no longer rely on the CPU node which is prone to error and will lead to a confusion in the DT because the cpufreq cooling device is also using it. Let initialize the cpuidle cooling device with the DT binding. This was tested on: - hikey960 - hikey6220 - rock960 - db845c
