Anas Nashif 8faca29fea tests/samples: fix usage of integration_platforms
integration platforms can't be filtered out, adapt tests so that those
platforms are always available for testing.

MPR Pressure Sensor
###################

Overview
********

This sample application periodically (1Hz) measures atmospheric pressure in
kilopascal. The result is written to the console.

References
**********

- MPR: https://sensing.honeywell.com/micropressure-mpr-series

Wiring
******

This sample uses an MPRLS0025PA00001A sensor controlled using the i2c
interface. Connect **VIN**, **GND** and Interface: **SDA**, **SCL**.

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

This project outputs sensor data to the console. It requires a sensor from the
MPR series.
It does not work on QEMU.
In the sample below the :ref:`arduino_due` board is used.
