Subject: drm/exynos/dsi: Remove error handling for bridge_node DT parsing
Git-commit: 0d51a0a534534c8b5d843620243e2370a3e87217
Patch-mainline: v4.13-rc3
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Remove the error handling of bridge_node because the bridge_node is
optional.
For example, In case of Exynos SoC, a bridge device such as mDNIe and
MIC could be placed between Display Controller and MIPI DSI device but
the bridge device is optional.
