phy: ti: j721e-wiz: Fix device node reference leak in wiz_get_lane_phy_types() 



The serdes device_node is obtained using of_get_child_by_name(),
which increments the reference count. However, it is never put,
leading to a reference leak.

Add the missing of_node_put() calls to ensure the reference count is
properly balanced.
