Subject: [RFC PATCH 8/9] ARM: dts: suniv: add initial DTSI file for suniv and F1C100s
As we have the support for suniv pin controller and CCU now, add a
initial DTSI for it.
F1C100s is one product with the suniv die, which has a 32MiB co-packaged
DDR1 DRAM chip. As there's nothing special for it, add a dummy DTSI file
for it.
