[PATCH v2] riscv: fix build failure with Canaan K210 SoC

[Damien Le Moal]

Fix riscv dts main Makefile to avoid build failures when
CONFIG_SOC_CANAAN is selected but CONFIG_SOC_CANAAN_K210_DTB_BUILTIN is
not set. In this case, the SoC device tree should not be built.
Avoid the failure by changing the canaan subdir inclusion based on the
CONFIG_SOC_CANAAN_K210_DTB_BUILTIN configuration option value instead
of on the value of the CONFIG_SOC_CANAAN configuration option.
