elog: Eliminate the second in memory copy of the event log.

The event log driver keeps two copies of the event log in memory, one to
    take the place of the historically memory mapped image of flash which is now
    read and written manually, and one originally intended to be an in memory
    cache of flash. Since both are now just copies in memory, there's no value in
    having them both and keeping them in sync.

Built and booted on Link. Ran mosys eventlog list. Added 2000 events to
    the log and ran mosys eventlog list again. Cleared the log by echoing a 1 into
    /sys/firmware/gsmi/clear_eventlog and ran mosys eventlog list again.
