riscv: dts: canaan: build all devicetress if SOC_CANAAN

Testing & checking the Canaan devicetrees is inconvenient as only the
devicetree corresponding to SOC_CANAAN_K210_DTB_BUILTIN will be built.
Change the Makefile so that all devicetrees are built by default if
SOC_CANAAN but only the one specified by SOC_CANAAN_K210_DTB_BUILTIN
gets built as an object.
