This PR adds support for Milk-V Duo S 64-bit RISC-V SBC, based on SOPHGO SG2000 SoC (T-Head C906 Core). Most of the code is derived from NuttX for Ox64 BL808. The source files are explained in the articles here: https://github.com/lupyuen/nuttx-sg2000 Modified Files: `boards/Kconfig`: Added Milk-V Duo S board `arch/risc-v/src/sg2000/sg2000_timerisr.c`: Fixed MTIMER_FREQ for sleep() to work correctly New Files in boards/risc-v/sg2000/milkv_duos: `src/sg2000_appinit.c`: Startup Code `include/board.h`: Milk-V Duo S Definitions `include/board_memorymap.h`: Memory Map `src/etc/init.d/rc.sysinit`, `rcS`: Startup Script `src/.gitignore`: Ignore the tmp filesystem `scripts/ld.script`: Linker Script `scripts/Make.defs`: Milk-V Duo S Makefile `src/Makefile`: Milk-V Duo S Makefile `Kconfig`: Milk-V Duo S Config `configs/nsh/defconfig`: Build Config for `milkv_duos:nsh` Updated Documentation: `platforms/risc-v/sg2000/index.rst`: New page for SOPHGO SG2000 SoC `platforms/risc-v/sg2000/boards/milkv_duos/index.rst`: Building and booting NuttX for Milk-V Duo S
