Bugfix bad resolution of compass LSM303AGR: The values of the variant LSM303AGR were more instabled compared to other variants. Root cause was that low power and high resolution are set in different registers and both options were enabled what is an invalid configuration => most likely the request for high resolution was ignored. To fix this the low power mode is only set in sleep and the high resolution is used in normal operation => compass performance same as in other variants.
