Johan Hovold 53693b3268 amba: tegra-ahb: Fix device leak on SMMU enable 
commit 500e1368e4 upstream.

Make sure to drop the reference taken to the AHB platform device when
looking up its driver data while enabling the SMMU.

Note that holding a reference to a device does not prevent its driver
data from going away.
