net: phy: realtek: register/unregister multiple drivers properly

Using phy_drivers_register/_unregister functions is proper way to
handle multiple PHY drivers registration. For Realtek PHY drivers
module, it fixes incomplete current error-handlings up and adds
missed unregistration for the RTL8201CP driver.
