elog: Stream line the elog driver.

The elog driver's design was a bit more elaborate than it really needed to be
    since it no longer had to keep track of multiple copies of the log in flash
    and also in memory. This change streamlines it by removing unnecessary
    compartmentalization of some bits of code, and some variables which tracked
    the last entry added which were never used.

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