Reactivate compass parameter stored in NVM: The calibration parameters are stored in NVM but the automatic restore function during startup was no longer active. As result the compass needed to be calibration after every RTE update. In addition compass HW was detected at every startup causing some i2c "trouble" because of adressing not available devices. The compass HW info is now stored together with the calibration parameters to avoid i2C problems.
