From: Mario Limonciello <mario.limoncie...@amd.com>
AMD RX580 when added AMD Phenom 2 has problems with overheating. This is
due to changes with PCIe dynamic switching introduced by commit
466a7d115326e ("drm/amd: Use the first non-dGPU PCI device for BW limits")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4098
Fixes: 466a7d115326e ("drm/amd: Use the first non-dGPU PCI device for BW
limits")
