Peter Bigot b314857099 treewide: use full path to kscan.h header
The build infrastructure should not be adding the drivers subdirectory
to the include path.  Fix the legacy uses that depended on that
addition.

KSCAN Interface
####################################

Overview
********

This sample demonstrates how to use the :ref:`KSCAN API <kscan>`.
Callbacks are registered that will write to the console indicating KSCAN events.
These events indicate key presses and releases.

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

The sample can be built and executed on boards supporting a Keyboard Matrix.
Please connect a Keyboard Matrix to exercise the functionality. You need to
obtain the right keymap from the vendor because they vary across different
manufactures.

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

.. code-block:: console

   KSCAN test with a Keyboard matrix
   Note: You are expected to see several callbacks
   as you press and release keys!
