Gerard Marull-Paretas c7b5b3c419 samples: migrate includes to contain <zephyr/...> prefix
In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:

```python
from pathlib import Path
import re

EXTENSIONS = ("c", "h", "cpp", "rst")

for p in Path(".").glob("samples/**/*"):
    if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
        continue

    content = ""
    with open(p) as f:
        for line in f:
            m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
            if (m and
                not m.group(2).startswith("zephyr/") and
                (Path(".") / "include" / "zephyr" / m.group(2)).exists()):
                content += (
                    m.group(1) +
                    "#include <zephyr/" + m.group(2) +">" +
                    m.group(3) + "\n"
                )
            else:
                content += line

    with open(p, "w") as f:
        f.write(content)
```

OpenAMP Sample Application using resource table
###############################################

Overview
********

This application demonstrates how to use OpenAMP with Zephyr based on a resource
table. It is designed to respond to the:

* `Linux rpmsg client sample <https://elixir.bootlin.com/linux/latest/source/samples/rpmsg/rpmsg_client_sample.c>`_
* `Linux rpmsg tty driver <https://elixir.bootlin.com/linux/latest/source/drivers/tty/rpmsg_tty.c>`_

This sample implementation is compatible with platforms that embed
a Linux kernel OS on the main processor and a Zephyr application on
the co-processor.

Building the application
*************************

Zephyr
-------

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/openamp_rsc_table
   :goals: test

Linux
------

Enable SAMPLE_RPMSG_CLIENT configuration to build and install
the rpmsg_client_sample.ko module on the target.

Running the sample
*******************

Zephyr console
---------------

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.

Linux console
---------------

Open a Linux shell (minicom, ssh, etc.) and insert a module into the Linux Kernel

.. code-block:: console

   root@linuxshell: insmod rpmsg_client_sample.ko

Result on Zephyr console on boot
--------------------------------

The following message will appear on the corresponding Zephyr console:

.. code-block:: console

   ***** Booting Zephyr OS v#.##.#-####-g########## *****
   Starting application thread!

   OpenAMP demo started
   Remote core received message 1: hello world!
   Remote core received message 2: hello world!
   Remote core received message 3: hello world!
   ...
   Remote core received message 100: hello world!
   OpenAMP demo ended.


rpmsg TTY demo on Linux console
-------------------------------

On the Linux console send a message to Zephyr which answers with the "TTY <add>" prefix.
<addr> corresponds to the Zephyr rpmsg-tty endpoint address:

.. code-block:: console

   $> cat /dev/ttyRPMSG0 &
   $> echo "Hello Zephyr" >/dev/ttyRPMSG0
   TTY 0x0401: Hello Zephyr
