Subject: drm/tilcdc: Remove redundant OF_DETACHED flag setting
Git-commit: 44cd3939c111b78a9fc6e3136fb0f9b6f475f68a
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

of_fdt_unflatten_tree() already sets the flag on this node to
OF_DETACHED, because of_fdt_unflatten_tree() calls
__unflatten_device_tree() with the detached bool set to true.
