drivers/elog/elog.c: Create extended event
For debug reasons, sometimes you not only want to log an event, but also
some extra information that would help debugging. Create an extended event
reporting event type with a dword complement, and define extended events
for failing to enter S3 due to pending wake event (one for pm1 and one for
gpe0).
BUG=b:111100312
TEST=Add a fake pending wake event, build and boot grunt, see the event in
eventlog.txt.
