Change in simtrace2[master]: cardem: Report the VCC voltage (if supported)

laforge has uploaded this change for review. ( https://gerrit.osmocom.org/c/simtrace2/+/26996 ) Change subject: cardem: Report the VCC voltage (if supported) ...................................................................... cardem: Report the VCC voltage (if supported) The SIMtrace2 protocol alwasy contained a field for the VCC voltage, the cardem firmware just never populated that field, even on those boards that use the ADC to determine its voltage.
