[PATCH 06/12] drm/amd/display: Reverting "Add connector to the state if DSC debugfs is set"

[Aurabindo Pillai]

From: Eryk Brol <eryk.brol at amd.com>

This reverts commit 39edb76689b8c9e41b1b9e2557da4897a405221b.

Reason for revert: Patch introduces performance issues and might
cause memory consistency problems with multiple connectors.
