drivers: net: cpsw: increment reference count on fixed-link PHY node
When a fixed-link sub-node exists in a slave node, the slave node
is also the PHY node. Since this is a separate use of the slave node,
of_node_get() should be used to increment the reference count.
Fixes: 1f71e8c96fc6 ("drivers: net: cpsw: Add support for fixed-link PHY")
