Patchset[1] for fix this issue currently landed in upstream,
so we backported them:

b3d71abd135e xhci: Poll for U0 after disabling USB2 LPM
f0c472a6da51 xhci: Return if xHCI doesn't support LPM
[Test]
With the above patch applied, run:
sudo fwts --s3-sleep-delay=30 --s3-multiple=30 -p s3
Can passed 30 times.
[Regression Potential]
Low, the patch is just like a safeguard,
doesn't really change any behavior.
[Reproduce Steps]
1. Install dell-bto-bionic-bolt-l-X51-20190720-56.iso
2. Upgrade kernel to 4.15.0-1080-oem
3. Boot the system with 4.15.0-1080-oem kernel
4. Insert SD card
5. Suspend the system to S3
