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.
