The G1 doesn't support mode2, despite advertising it.
The G1 chokes w/ an "Error 303" when we specify NMI mode 2. Adding a
quirk to drop that mode from the supported list (just use mode 1) allows
the G1 to properly deal with SMS.
Some Nokia modems only support "MT" as the incoming sms store.
Presumably the modem has some intelligence to pick the right store
depending on the SMS class. This means that oFono must now track
what the current store is, and issue a CPMS, CMGR & CMGD when a
CMTI notification arrives.
Since the PDU line doesn't have a prefix, the parser can get confused
if other unsolicited notifications arrive. There is already explicit
support for unsolicited notifications with PDU, so we use that
instead
