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)
```

BMI270: 6 axis inertial measurement unit
########################################

Description
***********

This sample application configures the accelerometer and gyroscope to
measure data at 100Hz. The result is written to the console.

References
**********

Wiring
*******

This sample uses the BMI270 sensor controlled using the I2C interface.
Connect Supply: **VDD**, **VDDIO**, **GND** and Interface: **SDA**, **SCL**.
The supply voltage can be in the 1.8V to 3.6V range.
Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up
resistors.

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

This project outputs sensor data to the console. It requires a BMI270
sensor. It should work with any platform featuring a I2C peripheral interface.
It does not work on QEMU.
In this example below the :ref:`nrf52840dk_nrf52840` board is used.
