We switch to the way it works in Android, short press (<2s) takes the target
to suspend and long press, >2s but <9s, performs a software controlled
power down.
Pressing longer than 9 seconds does the uncontrolled hardware power off
directly from the PMIC.

The suspend script did a ifup/ifdown on wlan0 to workaround issues we
had using wireless drivers on some platforms.
