[PATCH 3/3] G1: Add G1-specific SMS support

Hi Andres,

So as we discussed on IRC, this one should really be rolled up into the 
generic_at sms driver, since the only change of substance is the cnmi mode 
selection specific to the g1.  We need a driver quirk system to be figured out 
first though.
