[amdgpu][psr] Screen flickering/ tearing on 6.1/6.2/6.3 kernel

Bug description:
After upgrading from kernel 5.19.0-35-generic to 6.1.0-1007-oem there
is occasional screen flicker/ tear. It happens around every minute; it
seems connected to window/ pointer movement, but I have no clear way
of reproducing. Disruption is minor, but annoying.
I'm running 22.04 LTS on a new Thinkpad T14s with AMD Ryzen 6850u. The
system is fully functional. No crashes, nothing breaks.
Background on the use of 6.1.0-1007-oem: 5.19.0-35-generic breaks
suspend/ resume on my laptop, see
https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.19/+bug/2007718.
In a way, running 6.1 is a 'flight forward', since 5.15.0-67-generic
(previous 22.04.1 LTS kernel) works well, with working suspend/
resume, and without screen flicker. But that's an 'old' kernel now,
missing some nice improvements for the newer Ryzen APUs.
