Power Allocator governor is able to keep SOC temperature within a
defined temperature range to avoid SOC overheat and keep it's
performance. mt8173-cpufreq.c need to register its' own power model with
power allocator thermal governor, so that power allocator governor can
allocates suitable power budget to control CPU temperature.

Measure and create dynamic/static power model, and register cooling
device of_cpufreq_power_cooling_register for MT8173.
