link: TMP006 S0 param is uncalibrated by default
S0 values are incorrect and may even need to be calibrated on a
per-system basis. Set them to 0 by default so that the EC doesn't
return inaccurate remote temperature readings before calibration data
is sent.
BUG=chrome-os-partner:15174
BRANCH=link
TEST=manual
- temps -> remote temps are all not calibrated
- t6cal 1 s0 9301
- temps -> PCH D-Object temp now returns a temperature
