/**
* Wipes the flash config of UBX modules.
*
* Some UBX modules have a FLASH that allows to store persistent configuration that will be loaded on start.
* PX4 does override all configuration parameters it needs in RAM, which takes precedence over the values in FLASH.
* However, configuration parameters that are not overriden by PX4 can still cause unexpected problems during flight.
* To avoid these kind of problems a clean config can be reached by wiping the FLASH on boot.
*
* Note: Currently only supported on UBX.
