Move sophgo.yaml from riscv into soc/sophgo so that it can be shared for
all SoCs containing ARM cores as well. This already applies to SG2002.
Add SG2000 SoC, Milk-V Duo Module 01 and Milk-V Module 01 EVB.

Enable ARCH_SOPHGO, pinctrl (built-in, required to boot), ADC as module.
This defconfig is able to boot from SD card on Milk-V Duo Module 01
evalboard.
