Public bug reported:

[Impact]
Process of s3 resume take 7s and it's too long which is over 5s.

[Fix]
Reference link_active_reporting field of PCI device to determine whether delay 
is taken or not.
Actual delay would be determined by taking maximum between 100ms and pci 
device's d3cold delay. 

[test]
With the patch, the total time s3 resume is 3874.298 ms which is smaller than 
5s.

[Regression Potential]
Low. This patch only changes the rules to determine whether delay is taken or 
not.
Reference the right field(link_active_reporting), but not speed of pci device.
