[PATCH 0/1][SRU][OEM-OSP1-B] UBUNTU: SAUCE: Speed up the process of s3 resume

[Koba Ko]

BguLink: https://bugs.launchpad.net/bugs/1876844

[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]
Medium. 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.

  UBUNTU: SAUCE: pci: s3 resume takes too long time, 7s.
