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.

ams ens210 Relative Humidity and Temperature Sensor
###################################################

Overview
********

This sample application demonstrates how to use the ams ens210 sensor to
measure the ambient temperature and relative humidity.

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

This sample application uses the sensor connected to the i2c stated in the
ens210.overlay file.
Flash the binary to a board of choice with a sensor connected.
For example build for a nucleo_f446re board:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/ens210
   :board: nucleo_f446re
   :goals: build flash
   :compact:
