Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

ams ens210 Relative Humidity and Temperature Sensor
###################################################

Overview
********

This sample application demonstrates how to use the ams ens210 sensor to
measure the ambient temperature and relative humidity.

Building and Running
********************

This sample application uses the sensor connected to the i2c stated in the
ens210.overlay file.
Flash the binary to a board of choice with a sensor connected.
For example build for a nucleo_f446re board:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/ens210
   :board: nucleo_f446re
   :goals: build flash
   :compact:
