Bug Description
Several HP platforms have a design change that eDP is connected to DP1 instead of DP0.
Because of this amdgpu needs a quirk to know to find eDP on DP1.

Without these quirks the brightness can not be adjusted and display will be lost after S0i3.
Already backported to v6.14.4, v6.12.25, and the corresponding generic kernel versions are 6.14.0-17.17. linux/oracular version 6.11.0-26.26 has v6.12.18, and the latest HEAD has v6.12.23 so far.
