iface-modem: disable unsolicited 3GPP events during quick suspend/resume

Browse Source 
This introduces the "terse" mode during quick suspend/resume, right now
it is used by 3GPP interface to disable unsolicited events, but in
future it can be used by other interfaces as well.

This prevents device to wake-up from suspend for each unsolicited while
still allowing to wake up on calls or SMS messages.
