    realtek: pcs: rtl931x: drop sequence in favor of function
    
    Drop a register write sequence from the USXGMII setup for RTL931x in
    favor of using a function that is already present. From the name, the
    function initializes LEQ DFE. Though it's not yet clear what it exactly
    does, this is already better then having a sequence with no explanation
    somewhere in the code.
    
    Apparently, when this code was added, the function wasn't present
    but it's content was just added here as single usage.
