Changing the cuda TOPHUB version is also proposed in #3606

I suggest you revert the tophub changes, and keep the changes local to the conv2d_direct.py file, and change the title labels to [TOPI][FIX] Typo in schedule template for conv2d_direct

@cbalint13 you are also proposing a version change on CUDA tophub schedule; can you coordinate to serialize the changes?

• Will rebase everything once this very 3717 is merged.
  So please merge this first, I have more work pending on our side (even beyond the simple tophub update).

Thank you !

Are you suggesting that the schedule function schedule_conv2d_nchw in conv2d_direct.py using the wrong schedule config? From my understanding, all schedule configs with name top_nn_conv2d are consumed by schedul_conv2d_nchw.
