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)
```

BMM150 Geomagnetic Sensor
#########################

Overview
********

This sample application periodically reads magnetometer (X, Y, Z) data from
the first available device that implements SENSOR_CHAN_MAGN_* (predefined array
of device names). This sample checks the sensor in polling mode (without
interrupt trigger).

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

This sample application uses an BMM150 sensor connected to a board via I2C.
Sensor has multiple pins so you need to connect according to connection diagram given in
`bmm150 datasheet`_ at page 41.

Sample Output
=============
To check output of this sample , any serial console program can be used.
Here I am using picocom program to open output. Check which tty device it is.
In my case it is ttyACM0

.. code-block:: console

        $ sudo picocom -D /dev/ttyACM0

.. code-block:: console

        ( x y z ) = ( -0.390625  0.087500  -0.390625 )
        ( x y z ) = ( -0.275000  0.115625  -0.275000 )
        ( x y z ) = ( -0.281250  0.125000  -0.281250 )
        ( x y z ) = ( -0.287500  0.134375  -0.287500 )
