thermal: consider emul_temperature while computing trend

Browse Source 
In case emulated temperature is in use, using the trend
provided by driver layer can lead to bogus situation.
In this case, debugger user would set a temperature value,
but the trend would be from driver computation.

To avoid this situation, this patch changes the get_tz_trend()
to consider the emulated temperature whenever that is in use.
