thermal/intel/intel_soc_dts_iosf: Fix reporting wrong temperatures

commit 0bb619f9227aa370330d2b309733d74750705053 upstream.

Since commit 955fb8719efb ("thermal/intel/intel_soc_dts_iosf: Use Intel
TCC library") intel_soc_dts_iosf is reporting the wrong temperature.

The driver expects tj_max to be in milli-degrees-celcius but after
the switch to the TCC library this is now in degrees celcius so
instead of e.g. 90000 it is set to 90 causing a temperature 45
degrees below tj_max to be reported as -44910 milli-degrees
instead of as 45000 milli-degrees.

Fix this by adding back the lost factor of 1000.
