ec/google/wilco: Add SMM handlers
Add EC handlers for specific SMM actions:
- on entry to sleep state tell the EC to save state and to prepare for
the host to enter sleep
- on ACPI enable/disable send command to the EC
- add a function to print SMI reasons when eSPI SMI is received
These need to be called by the mainboard handlers which will be done
when a board is added that uses this EC.
