Subject: [PATCH] suspend: add boot timer
The EG25 modem needs at least 2 minutes after indicating 'RDY'
to be fully operational. If the modem is suspended before that,
calls or texts may not be seen by the userspace.
This mostly occurs when a full reboot or poweroff/poweron
sequence of the phone is performed.
