Subject: drm/tinydrm: Drop driver registered message
MIME-Version: 1.0

Git-commit: 95a0cfe98ca07bb17dcdc285097a742a975456eb
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

No need to put out a driver registered message since drm_dev_register()
does that now. SPI speed is an important metric when dealing with
display problems, so retain that info.
