BugLink: https://bugs.launchpad.net/bugs/1936583

SRU Justification:

Impact:
The Tongfang GMxZGxx Barebone and propably also other new AMD based laptops fail to resume after suspend, and reboot instead with the 5.11 or earlier kernel.

Fix:
There is a quirk in newer linux kernel that can easily applied to 5.11 also.

Testcase:
A colleauge tested on a Tongfang GMxZGxx. The Ubuntu 5.11 kernel without the patch fails to resume, with the patch the issue is gone.
