This is where it is used, so move it into gmc init so that it will always be initialized in the right order. We already do this for other nbio and hdp callbacks so it's consistent with what we do on other IPs. This fixes the Unsupported Request error reported through AER during driver load. The error happens as a write happens to the remap offset before real remapping is done. Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373 The error was unnoticed before and got visible because of the commit referenced below. This doesn't fix anything in the commit below, rather fixes the issue in amdgpu exposed by the commit. The reference is only to associate this commit with below one so that both go together.
