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)
```

nRF LED matrix sample
#####################

Overview
********

This is a simple application intended to present the nRF LED matrix display
driver in action and to serve as a test ensuring that this driver is buildable
for both the :ref:`bbc_microbit_v2` and :ref:`bbc_microbit` boards.

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

The sample has been tested on the bbc_microbit_v2 and bbc_microbit boards,
but it could be ported to any board with an nRF SoC and the proper number
of GPIOs available for driving a LED matrix. To do it, one needs to add an
overlay file with the corresponding ``"nordic,nrf-led-matrix"`` compatible
node.

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

The code can be found in :zephyr_file:`samples/boards/nrf/nrf_led_matrix`.

To build and flash the application:
