Add "starfive,jh7110" to the compatible list as the least-compatible
(left-to-right order last item):

compatible = "starfive,visionfive-2-lite", "starfive,jh7110s",
"starfive,jh7110";

or if there is review feedback that no new compatible should be added,
then as usual for new JH-7110 boards:

compatible = "starfive,visionfive-2-lite", "starfive,jh7110";
