invensense icm20602 improvements

- checked register mechanism and simple watchdog
    - driver checks for errors gradually and can reconfigure itself
 - respect IMU_GYRO_RATEMAX at the driver level
 - fixed sensor INT16_MIN and INT16_MAX handling (y & z axis are flipped before publishing)
 - increased sensor_gyro_fifo max size (enables running the driver much slower, but still transferring all raw data)
 - PX4Accelerometer/PX4Gyroscope remove unnecessary memsets
