    realtek: pcs: add enum for port media
    
    The Realtek SDK includes a lot of code around specific port media,
    usually having quite some differences between 10G fiber, 1G fiber and
    DAC cables. For each type, several magic values are set which in the end
    usually make different kinds of links work optimal.
    
    While there is currently no way to get that media information from the
    kernel, add some fields as an enum to have a notion of different media
    kinds. In additional steps, code for the subtargets can be taken over
    from the SDK to handle different media.
