TS 102 232-1 CR0107 Fix references in TS 101 671 imports

Update the references to use existing references from TS 102 232-1
(if already present), or a new [XX..] reference to be updated in sync
with additions to TS 102 232-1 clause 2.

The translation is shown below.
In some cases, a newer document is used (e.g., 3GPP instead of GSM).
If the document ID isn't shown for the New reference, the Old
reference's document ID is implied.

Old (in TS 101 671)             New (in TS 102 232-1)
