All sensors were using legacy log module registeration method where LOG_LEVEL was defined before registeration. This method was error prone as it requires preserving includes order. Replaced with LOG_MODULE_REGISTER(foo, level). Signed-off-by: Krzysztof Chruscinski <krzysztof.chruscinski@nordicsemi.no>
