mb/google/hatch: Enable AP Wake from EC
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.
BUG=b:123325238,b:123325720
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.
