ELOG: Log run-time SMI southbridge events
Events are logged for SMIs that trigger ACPI sleeps state
entry and when the power button press triggers an SMI such
as at the developer/recovery screens.
Generate ACPI sleep state events and power button
events and verify they show up in the log:
153 | 2012-06-23 17:12:59 | ACPI Enter | S5
184 | 2012-06-23 17:15:50 | ACPI Enter | S3
216 | 2012-06-23 17:28:58 | Power Button
