[llvm] [AMDGPU][Docs] Fix broken link to HRF memory model reference (PR #88696)

[Fabian Ritter via llvm-commits]

https://github.com/ritter-x2a created https://github.com/llvm/llvm-project/pull/88696

The link to the Heterogeneous-race-free Memory Models ASPLOS'14 paper by Hower et al. pointed to a bogus website, probably because the domain ownership has changed.
This patch updates it to a version hosted on research.cs.wisc.edu.
