bug描述 Describe the Bug

海光DCU上设置-DWITH_CINN=ON，Paddle编译错误。
编译命令：cmake .. -DWITH_GPU=ON -DWITH_CINN=ON -DPY_VERSION=3.x
错误消息

    return std::clamp(ret, a, b);

这个是C17标准的用法，std::clamp，检查下你编译的时候是不是用的C14？

@risemeup1 确实是因为c版本，不过改成c17还是出错。
原因在cmake/hip.cmake

if(WITH_CINN)
  list(APPEND HIP_CXX_FLAGS -std=c++14)
else()
  list(APPEND HIP_CXX_FLAGS -std=c++17)
endif()

改成-std=c++17，出现了另一个错误：

CINN目前开源的代码还未支持DCU编译，后续功能会开源，请关注，谢谢
