    realtek: phy: cleanup RTL8214C configuration
    
    RTL8214C configuration is currently useless.
    
    - It uses register 29 (write only companion of ext. page register 30)
    - "configuration" only reads registers 2/3 and writes a message
    - "configuration" is run during probing
    
    Drop the useless coding. As this was the last consumer drop register
    29 define too.
