quectel: initialize call, phonebook and sms when ready

The Quectel M95 modem issues a "Call ready" notification when call and
phonebook are ready, so set up a listener for that.

The only way to know when sms is ready is to issue QINITSTAT queries.
Since sms is always ready after call and phonebook, the queries are
initiated after creating call/phonebook.
