* Currently only on heltec tracker, but could use ADC_USE_PULLUP on other boards that could benefit * Thanks @todd-herbert and @StevenCellist for the instructions ;-) * Remove nasty Heltec_wireless #ifdefs that got somehow added to Power.cpp, instead use proper variant defs * Cleanup adc enable/disable code a bit for less copy-paste cruft
