An external project needing something is not a reason to add methods in tree. It could be part of an argument to do so but in the context of this patch, this new RISC-V method is not needed and should be removed.

If you want to ease TVM's pain by upstreaming their changes you can do so, in a PR focused on that, with some in tree use case and testing.
