Multi gpiochip support for native environment (#5743)

* For each GPIO PIN, allow to specify gpiochip and line

* Added support for LLCC68 in native env.

* Removed one if by employing &&

* Fix for log, as std::string and not const char*

* Remove CH341 flag, enabling it for all LoRa chips

* Provide a default example
