Add error handling from calling fixed_phy_register.
It may return some error, therefore, need to check the status.
And fixed_phy_register needs to bind a device node for mdio.
Add the mac device node for fixed_phy_register function.
This is a reference to this function, of_phy_register_fixed_link().
