MC7455 location support

Hi!

I can look into it, given there is some description or specification of the loc service protocol I can use. Do you have any pointers? Unfortunately I don't think I can allow myself the time to do full reverse engineering of the modem communication, so some doc about the QMI messages for the loc service would be nice (I'm not even familiar with QMI itself). 

LG,
