[02/10] sim7100: wait for modem to start while enabling

Commit Message

The sim7100_enable() returns 0 just after queuing the AT+CFUN=1 command,
which ofono core interprets as the modem being powered up and in pre-sim
state. In fact, the pre-sim state isn't reached until the modem returns
OK, which is caught in cfun_set_on_cb() in sim7100.c.

Delay the transition from off to pre-sim until the respone is received
by return EINPROGRESS instead, and let the (existing)
ofono_modem_set_powered() call signal pre-sim to ofono core.
