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.
