reef: Prepare LID_OPEN GPIO for hibernation

Browse Source 
LID_OPEN gpio is interrupt trigger on both the edge. If the system is
hibernated when LID is open and then LID is closed, system wakes from
hibernation. Hence setting the LID_OPEN GPIO as interrupt raising before
hibernation so that system won't wake up upon LID close in hibernation.

BUG=chrome-os-partner:57221
BRANCH=none
TEST=Issued hibernate when LID is open, closed the LID after hibernation
     observed system won't boot back till LID is open again.
