media: platform: mtk-mdp3: fix device leaks at probe
Make sure to drop the references taken when looking up the subsys
devices during probe on probe failure (e.g. probe deferral) and on
driver unbind.
Similarly, drop the SCP device reference after retrieving its platform
data during probe to avoid leaking it.
Note that holding a reference to a device does not prevent its driver
data from going away.
