    realtek: setup cpu port in soc_info structure
    
    A lot of soc_info usage has been reorganized. Nevertheless there
    are some consumers left. A very critical one is the dsa/qos coding.
    It makes use of the cpu_port in this shared structure. This is
    totally broken as that info is never properly initialized. Fill
    the cpu_port according to the identified hardware.
    
    Remark: Looking at the prom.c history soc_info.cpu_port was never
    setup since the beginning of time. So no "fixes" tag here.
