[PATCH net 2/4] 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 there is no guarantee that the devres-managed struct
cpsw_phy_sel_priv will continue to be valid until this function returns
regardless of this change.

Fixes: 5892cd135e16 ("drivers: net: cpsw-phy-sel: Add new driver...")
