mec1322: Allow GPIO hibernate state to be specified at board-level
Add a new board-level function board_get_gpio_hibernate_state which can
optionally be defined to set the desired state of a GPIO during
hibernate.
BUG=chrome-os-partner:43807
TEST=Manual on Glados with subsequent commit. Run 'hibernate' on console,
verify that LED remains off. Press power button, verify that board wakes.
BRANCH=None
