[Skiboot] [PATCH v2 26/31] libstb/tss/tpmLogMgr: add support for EV_SEPARATOR events

[Claudio Carvalho]

The TpmLogMgr_genLogEventPcrExtend() function is used to generate EV_ACTION
events that will be recorded in the event log. However, skiboot must also
create and record an EV_SEPARATOR event for a clean handover to
skiroot kernel.

This adds the i_logType parameter to the TpmLogMgr_genLogEventPcrExtend()
function, thus it can also be used to generate EV_SEPARATOR events.
