Kevin O'Connor 36de6118c1 mcu: Limit ADC min/max range to a 16bit integer ...

Make sure the ADC range sent to the MCU can be encoded into a 16bit
integer.  Otherwise, if the provided min_temp/max_temp was outside the
range of possible values it could result in a spurious mcu shutdown.
In particular, the AD595 could not properly encode a min_temp of zero.
