    lantiq: activate noise margin delta for VDSL too
    
    Previously this was only activated for ADSL, this patch activates the
    same setting also for VDSL, this feature is also support for VDSL in the
    same way it works for ADSL.
    I tested it with DSL FW 5.7.9.5.1.7 against a Broadcom 177.140 DSLCO
    (Deutsche Telekom) and saw different data rates and Max. Attainable Data
    Rates depending on the ds_snr_offset settings I choose.
