This drivers allows a fixed framebuffer memory to be set by an additional
IORESOURCE_MEM resource. Thus add an example to the DT documentation.

Actually I stumbled myself over this wondering how can I use this specific

this as an example for other people maybe not that experienced on
device-tree.
