rambi: enable SCI and SMI gpios

Browse source 
Rambi has 3 pins that need to be configured for SCI and SMI:

1. GPIO_CORE[0] - runtime SCI pin
2. GPIO_SUS[7] - SMI for firmware lid events
3. GPIO_SUS[0] - wake pin for S3 wakes from EC.

Configure these pins now that the rest of the infrastructure
is in place. The one thing that is yet to work is runtime SCI
for lid events once booted.

BUG=chrome-os-partner:23505
BRANCH=None
TEST=built and booted. lid close at rec screen works. And wake
     from S3 with a keyboard press works.
