    powerpc/mpc5xxx: Add missing fwnode_handle_put()
    
    [ Upstream commit b9bbbf4979073d5536b7650decd37fcb901e6556 ]
    
    In mpc5xxx_fwnode_get_bus_frequency(), we should add
    fwnode_handle_put() when break out of the iteration
    fwnode_for_each_parent_node() as it will automatically
    increase and decrease the refcounter.
