net: ethernet: cpsw: fix erroneous condition in error check
[ Upstream commit ce16294fda230c787ce5c35f61b2f80d14d70a72 ]
The error check in cpsw_probe_dt() has an '&&' where an '||' is
meant to be. This causes a NULL pointer dereference when incomplet DT
data is passed to the driver ('phy_id' property for cpsw_emac1
missing).
