trace: thermal: add another parameter 'power' to the tracing function
This patch adds another parameter to the trace function: trace_thermal_power_devfreq_get_power(). In case when we call directly driver's code for the real power, we do not have static/dynamic_power values. Instead we get total power in the '*power' value. The 'static_power' and 'dynamic_power' are set to 0. Therefore, we have to trace that '*power' value in this scenario.
