qmi: activate default bearer context for LTE networks
When the modem attaches to an LTE network, a default bearer is automatically negotiated using the "defalt profile" settings. The QMI modem, however, does not given any explicit indication that the bearer exists; instead, we must assume its existence based on the network registration state. This patch extends the GPRS atom to signal the presence of a default bearer when it detects network connectivity on an LTE network.
