Maybe I should split this patch into different subsystems for better
review. I think at least drivers/soc/Makefile should changed to use
ARCH_CANAAN. Because we need some SoC drivers for K230 in the future.
And arch/riscv/Makefile should use SOC_CANAAN_K210 instead of
ARCH_CANAAN. Because we should avoid the M-Mode loader build for
other Canaan SoCs except for K210.
