In the long run, ARCH_SOPHGO will be used to enable all arm64 products 
under Sophgo (although only SG2000 is seen at present), so it is not 
good to limit it to SG2000.

So I suggest you modify the help description here and do not select 
these SG2000-specific configurations. The specific configuration can be 
enabled in defconfig. Please refer to the similar ARCH_SOPHGO processing 
in `arch/riscv/Kconfig.socs`.
