Jacob Dahl b0ede4ff21 hwdef: ARK_RTK_GPS: do not save u-blox config to receiver flash
AP_Periph configures the ZED-F9P from its own parameters at every boot, so
the copy saved into the receiver's flash is never the source of truth. Each
save is a UBX-CFG-CFG sent with no deviceMask, which the receiver applies to
BBR and flash: an erase and program of the whole flash configuration layer.

That write lands 5s or more after startup and only while disarmed, which is
exactly when a unit is likely to be unplugged, and the receiver shares the
board supply so there is no orderly shutdown. A power cut mid-save can leave
the configuration layer corrupt.

Defaulting GPS_SAVE_CFG to 0 keeps the receiver configured from RAM on every
boot and removes the write.

OpenSSF Best Practices

ArduPilot is the most advanced, full-featured, and reliable open source autopilot software available. It has been under development since 2010 by a diverse team of professional engineers, computer scientists, and community contributors. Our autopilot software is capable of controlling almost any vehicle system imaginable, from conventional airplanes, quad planes, multi-rotors, and helicopters to rovers, boats, balance bots, and even submarines. It is continually being expanded to provide support for new emerging vehicle types.
