Bjorn Helgaas d08c30d7a0 Revert "PCI/PM: Assume ports without DLL Link Active train links in 100 ms"
This reverts commit ec411e02b7.

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:

  nouveau 0000:01:00.0: fifo: PBDMA0: 01000000 [] ch 0 [00ff992000 DRM] subc 0 mthd 0008 data 00000000

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 ec411e02b7 solved the problem.  Unfortunately,
this revert will reintroduce the "Thunderbolt bridges take long time to
resume from D3cold" problem:
