Lee Lup Yuen 8e30c13441 arch/risc-v: Add support for SOPHGO SG2000 SoC (T-Head C906) 
This PR adds support for the SOPHGO SG2000 SoC, based on T-Head C906 64-bit RISC-V Core. This will be used by the upcoming port of NuttX for Milk-V Duo S SBC.

Most of the code was derived from NuttX for Ox64 BL808. The source files are explained in the articles here: https://github.com/lupyuen/nuttx-sg2000

`Kconfig`: Added ARCH_CHIP_SG2000 for SG2000 SoC
