Subject: [PATCH] Revert "drm/amd/display: Fix memory leaks in S3 resume"

This reverts commit a135a1b4c4db1f3b8cbed9676a40ede39feb3362.

This leads to blank screens on some boards after replugging a display. Revert until we understand the root cause and can fix both the leak and the blank screen after replug.
