FSP/ELOG: Improve elog event states
ELOG enables event notification once new log is available. And this
will be disabled after host completes reading logs (it has to complete
both fsp_opal_elog_info and fsp_opal_elog_read).
Ideally we should disable notification as soon as host consumes event
(after fsp_opal_elog_info). Also if host fails to call fsp_opal_elog_read
(ex: situations like duplicate event), then we endup keeping notification
forever.
This patch introduces new ELOG state (ELOG_STATE_HOST_INFO). As soon
as host consumes event elog will move to this new state so that event
notification is disabled.
