In order for sun4i-drm to be able to choose correct LCD configuration,
two different device trees should be present, one for a resolution.
Add stub device trees for two resolutions.
As the sun4i-drm driver still has some problems to support the LCDs,
the
real LCD device nodes are not added to the device tree files.

This should be an overlay, ideally applied by the bootloader.
I think this is not suitable for overlay.
The two kind of Q8 tablets are not compatible at all, and they
should both have a suitable device tree. The old DT without
resolution is only kept for backward compatibility.
