Similar to cpufreq_cooling_register, this function registers a cpufreq
cooling device. Using this function, the cooling device will
implement the power extensions by using a simple cpu power model. The
cpus must have registered their OPPs using the OPP library.
The additional parameters are needed for the power model (See 2. Power
models). "capacitance" is the dynamic power coefficient (See 2.1
Dynamic power). "plat_static_func" is a function to calculate the
static power consumed by these cpus (See 2.2 Static power).

The `plat_static_func` parameter of `cpufreq_power_cooling_register()`
is optional. If you don't provide it, only dynamic power will be
considered.
