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.

PS/2 Interface
####################################

Overview
********

This sample demonstrates how to use the :ref:`PS/2 API <ps2_api>`.
Callbacks are registered that will write to the console indicating PS2 events.
These events indicate mouse configuration responses and mouse interaction.

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

The sample can be built and executed on boards supporting PS/2.
It requires a correct fixture setup. Please connect a PS/2 mouse in order to
exercise the functionality.
For the correct execution of that sample in twister, add into boards's
map-file next fixture settings::

      - fixture: fixture_connect_mouse

Sample output
=============

.. code-block:: console

   PS/2 test with mouse
   Note: You are expected to see several interrupts
   as you configure/move the mouse!
