x_nucleo_iks01a3 shield: STM LSM6DSO sensor does not work after h/w or s/w reset

[avisconti]

LSM6DSO sensor on x_nucleo_iks01a3 shield does not work anymore after reset.

Steps to reproduce the behavior:
Plug the x_nucleo_iks01a3 shield on an arduino compatible board (e.g. nucleo_f401re).

Then:

1. cd .../zephyrproject/zephyr/samples/shields/x_nucleo_iks01a3/standard/

2. mkdir build && cd build

3. cmake -DBOARD=nucleo_f401re ..

4. make

5. see error on console output::
