Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

RPMsg Service sample Application
################################

Overview
********

RPMsg Service is an abstraction created over OpenAMP that makes initialization
and endpoints creation process easier.
This application demonstrates how to use RPMsg Service in Zephyr. It is designed
to demonstrate how to integrate RPMsg Service with Zephyr both from a build
perspective and code.

Building the application for nrf5340dk_nrf5340_cpuapp
*****************************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: nrf5340dk_nrf5340_cpuapp
   :goals: debug

Building the application for mps2_an521
***************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: mps2_an521
   :goals: debug

Building the application for v2m_musca_b1
*****************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: v2m_musca_b1

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:

.. code-block:: console

Building the application for bl5340_dvk_cpuapp
**********************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: bl5340_dvk_cpuapp
   :goals: debug

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: bl5340_dvk_cpunet
   :goals: debug

Open a serial terminal (for example Minicom or PuTTY) and connect to the board
with the following settings on both serial ports:

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

When you reset the development kit after having flashed both the application
and network core images, the following messages (one for master and one for
remote) will appear on the corresponding serial ports:

.. code-block:: console
