Adds min_frequency and max_frequency to struct motion_sensor_t. New attributes min_frequency and max_frequency are now returned in ectool's MOTIONSENSE_CMD_INFO response. Incremented ectool's MOTIONSENSE_CMD_INFO version to version 3. Add constants for MIN_FREQUENCY and MAX_FREQUENCY to each sensor's header file. BRANCH=none BUG=chromium:615059 TEST=build/boot and verify MOTIONSENSE_CMD_INFO response on kevin, make buildall -j passes.
