So I've been going back and forth on this one and my opinion is we should not
do the poll in the core. The modem has to do it anyway, so let the modem do
it and tell us when it happens. Most vendors provide unsolicited notifications
for SIM Toolkit events anyway. Let us treat it the same way as voicecalls.
The standard does not define any unsolicited responses for call state
notifications, yet in practice all modem vendors provide this.
Keep this code around and let us re-examine this decision if we ever need to
implement POLLING ON / POLLING OFF / POLLING INTERVAL commands. Based on all
the vendor specific docs I have these are intercepted by the modem and we never
see them anyway.

So three things here: First the STK details should be moved to a separate atom
since they are highly vendor specific.
Second, why are we bothering with fetch, can't we simply use
ofono_sim_proactive_command_notify to send us the apdu directly?
And we should get rid of status if we're not doing polling.
