pre-provide the mvno data of the edited apn

For mvno, user can add or edit mvno data field.
Pre-provide the mvno data of the edited apn when the user selects
one of the mvno types.
For example if user choose gid, populate the data field with the
current sim's gid1 data, or if user choose the SPN option, fill
in data with the current carrier string. If IMSI, fill in imsi data.
