soc: apple: mailbox: fix device leak on lookup

Browse source

commit f401671e90 upstream.

Make sure to drop the reference taken to the mbox platform device when
looking up its driver data.

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.
