glados: make EC_SMI_L functional
Set the EC_SMI_GPI define to be GPP_E15 and route that GPIO for SMI generation. Also, the mainboard_smi_gpi_handler() was introduced on skylake in order to process any GPI that could generate an SMI. Switch to this handler so one can process the appropriate events. BUG=chrome-os-partner:43778 BRANCH=None TEST=Used 'lidclose' on EC command line during depthcharge to confirm EC_SMI_L generates SMI and shutdown happens.
