Subject: drm/msm/dsi: set encoder mode for DRM bridge explicitly
Git-commit: 425a2d24d5b3ee9efc7f490440bfa20ba9166548
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Currently, DRM bridge for DPU relies on the default video
mode setting to set the encoder mode.

Add an explicit call to set the encoder mode for bridges.

Changes in v3:
- None
