ubloxmodem: add lte atom driver
Adds U-Blox Toby L2 driver for setting the default APN via the
+UCGDFLT command. Currently only IPv4 is supported. APN is
not stored to modem's non-volatile memory. oFono will manage this
default APN via it's config storage.
When receiving an empty default APN, the value is reset.
