Log message:
disable Panel Self Refresh (PSR) in amdgpu
PSR is a power saving feature, previously enabled for
DCN >= 3.1.2 (YELLOW CARP / Rembrandt).
Disabling PSR avoids a problem encountered by robert@ on a
ThinkPad X13 Gen 6 (21RM) with GC 11.5.2, DCN 3.5.0.
If a reboot was attempted after X started, the machine would hang.
robert has patiently tried many PSR related patches, but nothing
besides disabling PSR entirely has helped.
