simtrace: Enable VCC detection via ADC (voltage dependent)

Browse Source 
SIMtrace should reject any card activation at 1.8V as it is a 3[.3]V device
without level shifters.  For this, we must include the ADC in
determining the VCC voltage.

FIXME: reporting uses raw ADC voltage, not the voltage before divider
