This gives the userspace (e.g. Replicant) a chance to fully handle the
pm_wakeup_event, before autosleep suspends the system alltogether
again.

This fixes suspend/resume on the OpenPhoenux GTA04, in combination with
the Replicant 4.2.2 userspace, which needs to execute this to stay
awake: 'echo on > /sys/power/state'
