drivers: net: cpsw: fix parsing of phy-handle DT property in dual_emac config
Commit 9e42f715264ff158478fa30eaed847f6e131366b ("drivers: net: cpsw: add
phy-handle parsing") saved the "phy-handle" phandle into a new cpsw_priv
field. However, phy connections are per-slave, so the phy_node field should
be in cpsw_slave_data rather than cpsw_priv.
This would go unnoticed in a single emac configuration. But in dual_emac
mode, the last "phy-handle" property parsed for either slave would be used
by both of them, causing them both to refer to the same phy_device.
Fixes: 9e42f715264f ("drivers: net: cpsw: add phy-handle parsing")
