Required kernel fixes (in linux-next):
* https://gitlab.freedesktop.org/agd5f/linux/-/commit/63d0b87213a0ba241b3fcfba3fe7b0aed0cd1cc5
* https://gitlab.freedesktop.org/agd5f/linux/-/commit/040fdcde288a2830edc31dd507963d6aadf990d2

[SRU Justification]
[Impact]
power-profiles-daemon >= 2.0 now utilizes AMD GPU panel_power_savings
sysfs entry to set desired panel power saving level. Related kernel
fixes are to be released in v6.9.
[Fix]
Two linux-next committed fixes are required. The first one introduces
panel_power_savings sysfs entry itself, and the second one extends
abmlevel sysfs entry to allow an auto mode.
[Test Case]
1. Check existence of panel_power_savings sysfs entry:
$ cat /sys/class/drm/card0-eDP-1/amdgpu/panel_power_savings
-1
2. Remove power cable and switch between power profiles from Power
Management settings. The content of above panel_power_savings sysfs
entry should be updated correspondingly.
[Where problems could occur]
While the abmlevel entry now has a different default value that allows
automatic power management, the behavior may differ from users'
expectation.
[Other Info]
power-profiles-daemon >= 0.20 is only available on Noble or later at
this moment, so only Noble/Unstable will be nominated for fix.
