Grzegorz Swiderski 6640c04df6 sysbuild: Remove IMAGES variable 
This variable was originally provided for two indended purposes:

  * Let users manually add a new image in a desired order in the list.
  * Let users set build-only images, which are excluded from the list.

Given the recent additions of the `sysbuild_add_dependencies()` function
and the `BUILD_ONLY` parameter, `IMAGES` should be considered obsolete.

Furthermore, the list of images added to sysbuild should be updated
automatically when calling `ExternalZephyrProject_Add()`. This is now
possible by using a GLOBAL property internal to sysbuild.

With that, the `IMAGES` variable can be removed. Its existing usage for
image ordering is replaced with `sysbuild_add_dependencies()` treewide.

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. 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:
