[PATCH 27/29] drm/amd/display: Explicitly call ->reset for each object

[Harry Wentland]

We need to avoid calling reset after detection. This is much simpler
if we call ->reset on the connector right after creation but before
detection. To stay consistent call ->reset on every other object
as well after creation.
