[mobile-broadband-provider-info] Fixed settings for Telenor Norway

Ventelo settings were being selected for Telenor customers:

http://www.ventelo.no/bedrift/kundeservice/mobil/oppsett/manuelt-oppsett/

It appears that both Telenor and Ventelo use mcc="242" mnc="01" but
a) according to wikipedia it's Telenor's MCC/MNC and b) Telenor is bigger
so let's fix it for Telenor customers and let those Ventelo customers with
242/01 enter MMS settings manually. That's the best we can do in the moment.
