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
