libstb/tss: update the list of event types supported
Skiboot, precisely the tpmLogMgr, initializes the firmware event log by
calculating its length so that a new event can be recorded without
exceeding the log size. In order to calculate the size, it walks through
the log until it finds an especific event type. However, if the log has
an unknown event type, the tpmLogMgr will not be able to reach the end
of the log.
This updates the list of event types with all of those supported by
hostboot. Thus, skiboot can properly calculate the event log length.
