Subject: drm/bridge/sii8620: add Kconfig dependency on extcon
Git-commit: 7a109673899b6d5b147307999efe2392181acee3
Patch-mainline: v4.17-rc5
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The driver can work with or without extcon framework, but if extcon is
build as module, sii8620 should be build as module as well.
