drm: Don't call drm_dev_set_unique from platform drivers
Since
commit e112e593b2
Author: Nicolas Iooss <nicolas.iooss_linux@m4x.org>
Date: Fri Dec 11 11:20:28 2015 +0100
drm: use dev_name as default unique name in drm_dev_alloc()
we're using a reasonable default which should work for everyone. Only
mtk, rcar-du and sun4i are affected, and as kms-only drivers without
any rendering support no one should ever care about the unique name
v2: Rebase on top of mediatek.
