1e5cd4adfc drm/amd/display: move panel replay out from edp
[WHY]
Panel Replay is not an eDP-specific function.

[HOW]
Create new Panel Replay source files and move the Panel Replay
functions from the eDP files to the new files. Additionally, create
a new link_service construct function to assign the related
function pointers.

hotplug detection. This change allows per dcn hpd handling consolidating
hpd code in link_encoder.

compiled as a user-mode library

[WHAT]
Rename link.h to link_service.h to avoid name collision
