iio: imu: mpu6050: Add support for the ICM 20600 IMU
The Invensense ICM-20600 is a 6-axis MotionTracking device that combines a
3-axis gyroscope and an 3-axis accelerometer. It is very similar to the
ICM20602 imu which is already supported by the mpu6050 driver. The main
difference is that the ICM-20600 has a different WHOAMI value.
