It strictly doesn't but most other drivers in the same Kconfig file
also depends on ARCH_something or SOC_something. In particular
RESET_K210 depends on SOC_CANAAN. I think this is to prevent
overwhelming the user with useless choices if they didn't enable the
relevant SoC, and for others there are the COMPILE_TEST option.
