I had tried this and there would be two problems with this script. First, the
later GSM firmware will fall into sleep mode, so we could not make sure if 
"echo AT at POFF" is successful or not each time. Besides each machine should have
its specific power management so I think this part should be done in machine
plugin within gsmd. Second,  "echo 0 > power_on" will cause kernel panic right
now,  I still have no idea why. Actually, we don't need to do that , when system
power off, the pin will still be pulled low.
