net: ethernet: ti: am65-cpsw-nuss: use of_platform_device_create() for mdio
The MCU CPSW expected to populate only MDIO device, but follow up patches will add "compatible" property to the MCU CPSW CPTS node which will cause creation of CPTS device and MCU CPSW init failure. Hence, switch to use of_platform_device_create() instead of of_platform_populate() for MDIO device population. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
