for #4154 use internal pull-ups to power ADC_Ctrl

Browse Source 
* 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
