Subject: Revert "amdgpu/dc: drop dml display_mode_support.c (v2)"
Git-commit: 78109d230b797077d58600694ca427b9830eb600
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
This reverts commit 5e0adbff084f33202db36be798c583a115990392.
Unfortunately these clash with our DML update from the HW guys.
Will attempt to reroll them after.
