thermal: intel: x86_pkg_temp_thermal: Fix bogus trip temperature

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.
