net: ethernet: ti: cpsw: fix device and of_node leaks
Make sure to drop the references taken by of_get_child_by_name() and bus_find_device() before returning from cpsw_phy_sel(). Note that holding a reference to the cpsw-phy-sel device does not prevent the devres-managed private data from going away. Fixes: 5892cd135e16 ("drivers: net: cpsw-phy-sel: Add new driver...")
