net: ethernet: ti: am65-cpsw: Lower random mac address error print to info

Using random mac address is not an error since the driver continues to
function, it should be informative that the system has not assigned
a MAC address. This is inline with other drivers such as ax88796c,
dm9051 etc. Drop the error level to info level.
