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:
