Tomasz Bursztyka 42b1d76d80 samples: Apply IPM callback signature change where relevant 
Applications using IPM callbacks get the imp device instance pointer
now through the callback. Which help to clarify a bit the code here and
there as well.

Fixes #26923

OpenAMP Sample Application
##########################

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.

Building the application for lpcxpresso54114_m4

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:
