[PATCH 1/2] iio: imu: st_lsm6dsx: add support to ISM330IS

[Lorenzo Bianconi <lorenzo@kernel.org>]

Add support to STM ISM330IS (accelerometer and gyroscope) Mems sensor.
The ISM330IS sensor can use LSM6DSO16IS as fallback device since it
implements all the ISM330IS features currently implemented in
st_lsm6dsx.

Datasheet: https://www.st.com/resource/en/datasheet/ism330is.pdf
