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.
