iio: imu: mpu6050: Add support for the ICM 20602 IMU
The Invensense ICM-20602 is a 6-axis MotionTracking device that combines a 3-axis gyroscope and an 3-axis accelerometer. It is very similar to the ICM-20608 imu which is already supported by the mpu6050 driver. The main difference is that the ICM-20602 has the i2c bus disable bit in a separate register.
