Subject: [PATCH net-next 2/3] net: phy: realtek: eliminate has_phycr2 variable

This variable is assigned in rtl821x_probe() and used in
rtl8211f_config_init(), which is more complex than it needs to be.
Simply testing the same condition from rtl821x_probe() in
rtl8211f_config_init() yields the same result (the PHY driver ID is a
runtime invariant), but with one temporary variable less.
