Subject: drm/i2c: tda998x: register bridge outside of component helper
Git-commit: 5a03f5346fedc8b5f1a8601aa46a0930ba56a7ae
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Register the bridge outside of the component helper as we have
drivers that wish to use the tda998x without its encoder.
