F1C100s is one product with the suniv die, which has a 32MiB co-packaged
DDR1 DRAM chip. As we have the support for suniv pin controller and CCU now, add a
initial DTSI for it.

Why do you need that fake clock?

You should have a compatible for that SoC there (possibly keeping the
A10 compatible if that makes sense).
