Aaron Durbin 84da959c69 rambi: update EC support
Fix the SMI and SCI gpios for Rambi. Also, add in the
EC callbacks for the SMI handler. Note that the handler
for GPI SMIs has not been tested yet as baytrail chipset
code  doesn't yet support setting up those configurations
yet.

BUG=chrome-os-partner:23505
BRANCH=None
TEST=Noted that SCI was enabled in /sys/firmware/acpi/interrupts
     for the EC's SCI GPI. Also was able to see Chrome EC messages
     with CONFIG_DEBUG_SMI and powering down at the dev screen.
