Instead of having a separate list of white-listed registers we can trivially move this to the common workarounds framework. This brings us one step closer to the goal of driving all workaround classes using the same code. v2: * Use GEM_DEBUG_WARN_ON for the sanity check. (Chris Wilson) v3: * API rename.
