thermal: intel: x86_pkg_temp_thermal: Fix bogus trip temperature
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.
Fixes: 8ef0ca4a177d ("Merge back other thermal control material for 6.3.")
