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.
