temp_metrics: tmp006 calibration update

Updated S0 calibration settings based on DVT3 systems.

De-activate the PCH sensor in the thermal loop as its accuracy is poor.

BUG=chrome-os-partner:9599
TEST=run "for i in {0..3}; do echo $i: && ectool tmp006cal $i; done" and make sure
the S0 values are the same as those programmed by temp_metrics.conf.
BRANCH=none
