board/kukui: Support ADC value for NC
When the components like LCM ID are not installed (i.e., NC), ADC will return some value with much larger variation from standard value (out of the tolerance we set). To support that, we should check tolerance only on non-NC voltages. Also improve the error messages so we can see the ADC raw values instead of simple assertion error (which makes debugging more difficult since we have to build another firmware image just to print the values). BUG=None TEST=Booted on Kukui and got correct SKU ID for NC LCMID.
