sample/shield: x-nucleo-iks01a3: add support to lis2de12 on DIL24 



The x-nucleo-iks01a3 shield is equipped with a DIL24 socket where
different compatible sensors may fit. This commit add support to
lis2de12 on DIL24 in such a way that, if sensor is not present, test
would just skip it and proceed. Other sensors may be added in future.

DIL24 socket

************



In addition to sensors on board it is possible to place any other compatible

sensor on DIL24 socket. The sample is written in such a way that, if sensor is

not present, it will just be skipped.



List of sensors currently supported on DIL24 by this sample:



- LIS2DE12
