temp_sensor: Separate ADC interface and thermistor maths
Separate the bd99992gw ADC interface from the NCP15WB thermistor
adc-to-temp maths so that the thermistor can be used with various
other interfaces.
BUG=chrome-os-partner:44764
TEST=make buildall -j
Manual on Glados. Boot to S0, run "temps".
Verify that temperatures start around 28C and begin to increase after
system is powered-on for a long duration.
