  Add NTC thermistor conversion builtin

This requires that the target define the necessary parameters to
permit conversion from ADC input values to degrees C. For example, the
Circuit Playground Express board has a thermistor with nominal 10kΩ at
25° and a B value of 3950 connected from Vcc to the analog input, and
a 10k resistor from there to ground. The target defines the following
values:
