ltq-adsl-app: sync annex option between from VDSL package

The adsl control app missed the activation of annex M and annex L in
the Annex A part, this now activates everything the firmware supports.
In Annex L type only the wide US (Mask1) was activated, now also the
narrow US (Mask2) version gets activated.
In addition annex J was also added.
