[PATCH] Revert "drm/amd/display: Enable cur_rom_en even if cursor degamma is not enabled"

[Rodrigo Siqueira]

This reverts commit 5aba567a2988400d4e01d44493c84bed92820d8d.

The original patch introduces cursor gamma issue to multiple
Linux compositors. For this reason this commit reverts this change.
