drm/amd/display: Add check for headless for idle optimization
[Why]
Currently idle worker thread that checks for HPD while system is in IPS2
only supports headless and static screen use-cases.
In other display-off scenarios hotplug may not work.
[How]
For display-off only allow idle optimization when no display is connected.
