Does the HE910 have a proper CFUN mode where it does not turn off the
SIM? You are making some nasty hacks because of it, and the other Telit
devices support this just fine.
This patch changes the Telit driver so it will not go immediately
to CFUN=4 after enable, but to wait for the post_sim state to be
reached before doing so. In addition, the HE910 might send QSS: 0
unsolicited reports while in CFUN=4 state... this patch makes it so
that these are ignored until the modem is onlined and the actual
SIM state can be queried again.
Also remember the modem can be 'Online' even without a SIM, or in
pre-SIM state for e.g. emergency calls. So much of the logic might break.
