rambi: mainboard EC - SCI and SMI fixes

As rambi is a baytrail board it doesn't have a dedicated wake pin.
Therefore, one needs to enable the proper GPIO to wake up the sytem
before going into S3.

BUG=chrome-os-partner:23505
BRANCH=None
TEST=Put system into S3. Keyboard press created wake event. Also, typed
     'lidclose' on EC console while at recovery screen. Machine properly
     shutdown.
