Gpio modify v4 (#3266)

Browse Source 
* Refactor GPIO handling for RFFC5072: update pin mappings and simplify initialization

* Refactor GPIO handling: replace portapack::gpio_dfu with dfu_button and clean up unused GPIOs

* Refactor MAX283x GPIO handling: update pin mappings and simplify initialization

* Refactor GPIO handling: update MAX2831 shutdown pin configuration

* Refactor GPIO handling: add MAX2831 RXHP and RXTX control, update related configurations

* Refactor MAX2831 frequency setting to include reference divider parameter and improve validation checks

* Refactor MAX2831 frequency setting to remove reference divider parameter and improve frequency validation

* copilot
