Johan Hovold 6c66212b41 drm/tegra: dsi: fix device leak on probe 
[ Upstream commit bfef062695 ]

Make sure to drop the reference taken when looking up the companion
(ganged) device and its driver data during probe().

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