Before getting into wayland problems, you should find out if the vivante
eglfs integration supports dual screen or not. I recall there were
patches for it, not sure if they were up-streamed.
Once you have that sorted out, it should just work for wayland too: Use
1 compositor with two QWindows, one on each screen.
Here's an example of such setup:
