thermal: cpu_cooling: Make the power-related code depend on IPA
The core CPU cooling infrastructure has power-related functions that have only one client: IPA. Since there can be no user of those functions if IPA is not compiled in, make sure to guard them with checks on CONFIG_THERMAL_GOV_POWER_ALLOCATOR to not waste space unnecessarily.
