Johan Hovold e4077fcb14 mfd: altera-sysmgr: Fix device leak on sysmgr regmap lookup 
commit ccb7cd3218 upstream.

Make sure to drop the reference taken to the sysmgr platform device when
retrieving its driver data.

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

Fixes: f36e789a1f ("mfd: altera-sysmgr: Add SOCFPGA System Manager")
