Radoslaw Koppel d1a93c1426 drivers: sensor: Const sensor trigger data in trigger handler

This commit adds const modifier in second argument for
sensor trigger handler.
There is no reason to modify this data and this change
would allow to store trigger configuration also in FLASH.

Fixes: #38929

SM351LT: Magnetoresistive Sensor Example
########################################

Overview
********

This sample application periodically polls an SM351LT magnetoresistive sensor
and displays if a magnet near to the sensor, via the console.

Requirements
************

This sample uses the Honeywell SM351LT sensor.
