    realtek: pcs: add missing SerDes modes
    
    100Base-X mode was missing before in the enum rtpcs_sds_mode. So add it
    to be able to support this mode too. Handle this mode in the
    _determine_hw_mode mapper.
    
    10G_QXGMII mode was missing in the mode mapper. Add it and map it to
    USXGMII_10GQXGMII mode.
