Ilya Bakoulin e8bffa52e0 drm/amd/display: Don't try AUX transactions on disconnected link
[Why]
Setting link DPMS off in response to HPD disconnect creates AUX
transactions on a link that is supposed to be disconnected. This can
cause issues in some cases when the sink re-asserts HPD and expects
source to re-enable the link.

[How]
Avoid AUX transactions on disconnected link.
