rambi: add chromeos EC support

As rambi has the ChromeOS EC on it the EC needs to
    be configured properly. Do this along with updating the
    ChromeOS support for passing on write protect state, recovery
    mode and developer mode.

BUG=chrome-os-partner:23387
    BRANCH=None
    TEST=Built and booted to depthcharge. EC software sync appears to
         work correctly. Additionaly, 'mainboard_ec_init' appears in
         the console output.
