drm/amdgpu/nv: Apply ASPM quirk on Intel ADL + AMD Navi

S2idle resume freeze can be observed on Intel ADL + AMD WX5500. This is caused by commit 0064b0c ("drm/amd/pm: enable ASPM by default"). The root cause is still not clear for now. So extend and apply the ASPM quirk from commit e02fe3b ("drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systems"), to workaround the issue on Navi cards too.
