Your patch contains both "remove unused #define" and "support new hardware"
parts. I am not sure that the former is adequate for submission until
net-next opens.

static void rtl8201f_page_select(struct phy_device *phydev, int page) ?

         ^^ -> missing space.

Please propagate phy_driver_register error code.

Unbalanced error paths.

Code duplication.

You may use an array of phy_driver for realtek_{init/exit}
