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.

X-NUCLEO-IKS02A1 shield: Standard (Mode 1) sample
#################################################

Overview
********
This sample is provided as an example to test the X-NUCLEO-IKS02A1 shield
configured in Standard mode (Mode 1).
Please refer to :ref:`x-nucleo-iks02a1` for more info on this configuration.

This sample enables all sensors of a X-NUCLEO-IKS02A1 shield, and then
periodically reads and displays data from the shield sensors:

- IIS2MDC 3-Axis magnetic field intensity
- IIS2DLPC 3-Axis acceleration
- ISM330DHCX 6-Axis acceleration and angular velocity

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

This sample communicates over I2C with the X-NUCLEO-IKS02A1 shield
stacked on a board with an Arduino connector. The board's I2C must be
configured for the I2C Arduino connector (both for pin muxing
and devicetree). See for example the :ref:`nucleo_f401re_board` board
source code:

- :file:`$ZEPHYR_BASE/boards/arm/nucleo_f401re/nucleo_f401re.dts`
- :file:`$ZEPHYR_BASE/boards/arm/nucleo_f401re/pinmux.c`

Please note that this sample can't be used with boards already supporting
one of the sensors available on the shield (such as disco_l475_iot1)
as sensors multiple instances are not supported.

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

This sample runs with X-NUCLEO-IKS02A1 stacked on any board with a matching
Arduino connector. For this example, we use a :ref:`nucleo_f401re_board` board.
