Johan Hovold 9cb4deb883 drm: sti: fix device leaks at component probe ...

commit 620a8f1311 upstream.

Make sure to drop the references taken to the vtg devices by
of_find_device_by_node() when looking up their driver data during
component probe.

Note that holding a reference to a platform device does not prevent its
driver data from going away so there is no point in keeping the
reference after the lookup helper returns.
