Calibrate IR temperature sensors for Link DVT

Browse Source 
The TMP006 IR sensors are calibrated against the temperature measured on
the *external* side on the casing using a thermocouple stick at the
vertical of the sensor.

The hinge sensor is sending back strange values, and the Tobject from
there should not be trusted.

The DC-Jack C-case sensor is not calibrated (and will be removed soon).

BUG=None
TEST=on Link DVT, compare EC temperature values against thermocouple
readings.
