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

OpenAMP Sample Application
##########################

Overview
********

This application demonstrates how to use OpenAMP with Zephyr. It is designed to
demonstrate how to integrate OpenAMP with Zephyr both from a build perspective
and code.

Building the application for lpcxpresso54114_m4
***********************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/openamp

Open a serial terminal (minicom, putty, etc.) and connect the board with the
following settings:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

Reset the board and the following message will appear on the corresponding
serial port, one is master another is remote:
