riscv: dts: sophgo: Move all soc specific device into soc dtsi file

Although the cv1800b/cv1812h/sg2000/sg2002 share most peripherals,
some basic peripherals, like clock, pinctrl, clint and plint, are
not shared. These are caused by not only historical reason (plic,
clint), but also the fact the device is not the same (clock, pinctrl).

It is good to override device compatible when the SoC number is small,
but now it is a burden for maintenance, and it is kind of annoyed to
explain why using override. So it is time to move this out of the
common peripheral header.

Move all soc related peripheral device from common peripheral header
to the soc specific header to get rid of most compatible override.
