Initialize EC_PCH_WAKE_ODL GPIO to make sure that ec events will wake
the AP from suspend.  Also create a task to initialize the hostevent
wake mask properly.

BRANCH=None
TEST=from AP console: powerd_dbus_suspend
     from EC console: hostevent (make sure wake mask set)
     from EC console: gpioset PCH_WAKE_L 0
     Make sure device wakes up
     Also, checked to make sure keyboard press wakes up
     device from S3.
