6.12-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 043c87d7d56e135393f8aab927148096e2d17589 ]
DCE 6 was not advertised as being able to support VRR, so let's mark it as unsupported for now.
The VRR implementation in amdgpu_dm depends on the VUPDATE interrupt which is not registered for DCE 6.
