    realtek: pcs: rtl931x: merge and drop unused helper
    
    Merge the unused helper 'rtpcs_931x_sds_fiber_disable' into Fiber mode
    setting, and drop the helper itself. As with the MII helper in a
    previous commit, functionality is basically the same just with a value
    for OFF mode. If functionality is required later, Fiber mode setting can
    be used with the OFF mode instead of carrying the unused helper until
    it's used.
