Subject: drm/amd/display: Use TPS4 instead of CP2520_3 for phy pattern 7
Git-commit: 78e685f9a385eb984f69720e463878e5c3ae80b7
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
[Description]
We originally use TPS4 phy test pattern for test pattern 7.
On RV we switched to a new method to use CP2520.
CP2520 should produce the same result.
However in reality, it fails DP PHY automation test.
We use the original method instead.
