[PATCH] Telit plugin: add load_supported_bands interface

[Carlo Lobrano]

Well, have you ever felt so sure about one thing and then talking to
someone about it you realize that was wrong? I was so sure that parsing the
response, working out the LTE bands from that number and mapping the BND
values to MM bands would have been more difficult than just hardcode the
supported bands, that I did not consider it as a solution. Now I made some
design and it should be feasible. Sorry for the mess, I will propose
another patch.
