iio: imu: Add driver for BMI323 IMU 



The Bosch BMI323 is a 6-axis low-power IMU that provide measurements for
acceleration, angular rate, and temperature. This sensor includes
motion-triggered interrupt features, such as a step counter, tap detection,
and activity/inactivity interrupt capabilities.

The driver supports various functionalities, including data ready, FIFO
data handling, and events such as tap detection, step counting, and
activity interrupts.
