From: Claudio Carvalho <cclaudio at linux.vnet.ibm.com>
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.
