In design, TVM requires users to manually choose their target device. The `TVMContext` object has two structure members that are `device_type` and `device_id`.
If not specified, it's natural to choose the first one in default.

In `src/runtime/opencl/opencl_device_api.cc`, we can find some runtime functions that check the device information.
