google/reef: Add mainboard handler function for gpio SMI 

This patch adds mainboard_smi_gpi_handler which handles the
SMI event. This can happen in situations like lidclose and
system goes to shutdown.

BUG=chrome-os-partner:54977
TEST=When system is in firmware mode executing the command
     lidclose from ec console shuts down the system.
