In the macb binding documentation "phys" is an optional property. Make implementation in line with it. This change allows the traditional flow in which first stage bootloader does PS-GT configuration to work along with newer use cases in which PS-GT configuration is managed by the phy-zynqmp driver. It fixes below macb probe failure when macb DT node doesn't have SGMII phys handle.
