    realtek: rtl838x: fix lan9 and lan10 on Netgear GS110TUP
    
    The GS110TUP's lan9 port is connected via a QSGMII PHY to SERDES 2, and
    therefore should use the SWITCH_PORT_SDS macro instead of SWITCH_PORT. This
    was missed in e956adfe because the GS110TUP is not particularly well
    documented and the old code was confusing.
    
    lan10 is an SFP and doesn't have an onboard PHY, so also remove its
    associated PHY references and update it to match other devices' SFP ports.
