6.6-stable review patch. If anyone has any objections, please let me know.

commit cf948c8e274e8b406e846cdf6cc48fe47f98cf57 upstream.
The tj_max value obtained from the Intel TCC library are in Celsius, whereas the thermal subsystem operates in milli-Celsius.
This discrepancy leads to incorrect trip temperature calculations.
Fix bogus trip temperature by converting tj_max to milli-Celsius Unit.
