[Feature] 海光DCU简单测试，希望能支持

### Motivation

我希望在海光的DCU上能拉起服务
```bash
lmdeploy serve api_server /data/models/qwen/Qwen2-7B-Instruct \
> --model-name Qwen2-7B-Instruct \
> --server-port 8000 \
> --tp 2

```
但当我访问服务时：
```bash
curl "http://localhost:8000/v1/chat/completions" \
> -H "Content-Type: application/json" \
> -H "Authorization: Bearer replace_api_key" \
> -d '{
> "messages": [
> {
> "role": "system",
> "content": "You are a helpful assistant."
> },
> {
> "role": "user",
> "content": "你好，你是谁？你会做什么？"
> }
> ]
> }'
```
服务端coredump了
