[nv14] Make Ghost menu work with joystick trims (#1416)

* Update radio_ghost_module_config.cpp

* Update board.h

* Update keys_driver.cpp

* Auto-formatting

* Add functions simply so gtests compiles

* Update board.h

define TRIMS_EMULATE_BUTTONS to avoid HW dependent defines in other code

* Update radio_ghost_module_config.cpp

Use TRIMS_EMULATE_BUTTONS rather than PCBNV14

* `simu` code behind build flag also
