LoongArch: dts: Add new supported device nodes to Loongson-2K2000
By now, more Loongson-2K2000 related drivers are supported, such as clock controller and thermal controller. So we add these device nodes to the Loongson-2K2000 dts file. Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
