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.
