skylake: Add support for eSPI SMI events
Add the necessary infrastructure to support eSPI SMI events,
and a mainboard handler to pass control to the EC.
BUG=chrome-os-partner:58666
TEST=tested on eve board with eSPI enabled, verified that lid
close event from the EC during firmware will result in an SMI
and shut down the system.
