Add device tree bindings for the StarFive JH7110S SoC
and the VisionFive 2 Lite board equipped with it.

JH7110S SoC is an industrial SoC which can run at -40~85 degrees centigrade
and up to 1.25GHz. Its CPU cores and peripherals are mostly similar to
those of the JH7110 SoC.

I suggest adding starfive,jh7110 as a fallback here, as it's the SoC
best known to most softwares, and JH7110S shouldn't have any difference
to JH7110 other than binning.

NAK, it is said the operating parameters of jh7110s are distinct from
jh7110. You would have to show that it is safe to operate the jh7110s
with the operating parameters of the jh7110. If anything this would be
the inverse, some jh711x (or even j71xx to include jh7100) common
description with fallback operating parameters? And to add this common
fallback with jh7100 (?), jh7110, jh7110s  -E

How "mostly" is mostly? Are there memory map or capability differences?
