mb/google/eve: Implement EC device events for S3 wake
Add support for waking from and logging device events that originate in the Embedded Controller. As this device uses Deep S3 it relies on the EC to wake the AP from the trackpad and DSP wake sources. BUG=b:30624430 TEST=manual testing on Eve: wake from Deep S3 via trackpad and DSP and verify the event log contains the expected device event.
