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.

MS5837 Sensor Sample
####################

Overview
********

This sample application retrieves the pressure and temperature from a MS5837
sensor every 10 seconds, and prints this information to the UART console.

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

- `nRF52840 Preview development kit`_
- MS5837 sensor

Wiring
******

The nrf52840 Preview development kit should be connected as follows to the
MS5837 sensor.

+-------------+----------+
| | nrf52840  | | MS5837 |
| | Pin       | | Pin    |
+=============+==========+
| P0.3        | SCL      |
+-------------+----------+
| P0.31       | SDA      |
+-------------+----------+

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

Build this sample using the following commands:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/ms5837
   :board: nrf52840dk_nrf52840
   :goals: build
   :compact:

See :ref:`nrf52840dk_nrf52840` on how to flash the build.
