Bug description:
For Jammy/Kinetic SRU
[Impact]
While doing some tests such as suspend/resume or CPU stress tests the system
would hang.
[Fix]
The 2 commits fix the issue, but still not get accepted yet.

https://patchwork.ozlabs.org/project/linux-pci/patch/20220509073639.2048236-1-kai.heng.f...@canonical.com/
So, I created a DMI quirk to make the patches only affects on listed
platforms.
[Test]
Verified on the failed machines and ODM also verified on their side.
[Where problems could occur]
The patches only affects on the listed platforms, and won't affect other
platforms.

[Where problems could occur]
The 2 patches look pretty safe to me, they try to preserve the ASPM state of
devices.
