Wake keyboard task when lid opens
If keyboard scanning is active when the lid closes, it will disable
scanning put the scan task to sleep. We need a corresponding task
wake when the lid opens, or scanning will be stuck off (until
something else happens, like poking the power button).
BUG=chrome-os-partner:23032
BRANCH=wolf
TEST=Hold down a key. Use a magnet to trigger the lid switch. Scanning
should stop while the lid is "closed", and restart when the magnet is
moved to "open" the lid again.
