Milk-V Duo[1] board is an embedded development platform based on the
CV1800B[2] chip. Add minimal device tree files for the development board.
Currently, now it's supported to boot to a basic shell.

NOTE: this series is based on the SG2042 upstream series for the vendor
prefix and ARCH_SOPHGO option.
