Revert "PCI/PM: Assume ports without DLL Link Active train links in 100 ms"
This reverts commit ec411e02b7a2e785a4ed9ed283207cd14f48699d.
Patrick reported that this commit broke hybrid graphics on a ThinkPad X1
Extreme 2nd with Intel UHD Graphics 630 and NVIDIA GeForce GTX 1650 Mobile:

Karol reported that this commit broke Nouveau firmware loading on a Lenovo
P1G2 with Intel UHD Graphics 630 and NVIDIA TU117GLM [Quadro T1000 Mobile]:
nouveau 0000:01:00.0: acr: AHESASC binary failed
In both cases, reverting ec411e02b7a2 solved the problem. Unfortunately,
this revert will reintroduce the "Thunderbolt bridges take long time to
resume from D3cold" problem:
