Daniel DeGrasse 7cbdbaf146 samples: ipc: openamp: fix build for IMXRT11xx 
Fix build for IMXRT11xx SOCs. The ARM MPU header was missing for the CM4
board overlays, add the required header so the sample can build.

.. zephyr:code-sample:: openamp
   :name: OpenAMP
   :relevant-api: ipm_interface

   Send messages between two cores using OpenAMP.

Overview
********

This application demonstrates how to use OpenAMP with Zephyr. It is designed to
demonstrate how to integrate OpenAMP with Zephyr both from a build perspective
and code. Note that the remote and primary core images can be flashed
independently, but sysbuild must be used in order to build the images.

Open a serial terminal (minicom, putty, etc.) and connect the board with the
following settings:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

Reset the board and the following message will appear on the corresponding
serial port, one is master another is remote:
