PhyVersoBSP: Implemented request_stop_transaction via external push buttons connected to SOM GPIOs #791

Closed rckstrh closed 2 days ago

Describe your changes

These changes were implemented to be able to request a stop of a charging session by applying a digital signal to one of the 5V tolerant buffered SOM inputs. GPIO banks/pins as well as signal polarity are configurable via EVerest config parameters. The request_stop_transaction functionality via GPIO is by default disabled because input pins are floating due to missing pull resistors on phyVERSO HW revision 1. The GPIO inputs are getting debounced in software with currently ~160ms duration needed to register a stable state.
