    kernel: porting: Add disclaimer regarding the differences with upstream files
    
    This is a way to mitigate the issue of proposing non-official code. The
    other way would be to revert this patch and manually copy the four next
    DT snippets from the sources to only share 100% upstream code.

+  Disclaimer: while the way of describing a board has slightly evolved
+  over the past years, the official Crystalfontz support has not. As our
+  incentive is to show up-to-date code and share best practices, the
+  next snippets of code may diverge a little compared to the upstream
+  files.
