Subject: drm/amd/display: Add DIGD case when getting retimer settings
Git-commit: 4e527c01aa7a31b7aad98fa5493944891b69238d
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

One of the HDMI ports map to DIGD, which we did not map to DP3 ext
HDMI settings. Add the DIGD case so that we can get proper retimer
settings from SBIOS for that port.
