From: Ashish Jain <ashish.j...@nxp.com>
Removing use of link data under evq_info_t structure which was
used to check whether the the associated evq has been linked
or not. Since, an evq can be linked to multiple event ports,
thus setting the link variable only allowed the first event
port to be associated with the evq. This led to huge performance
drop in case of multiple event ports as I/O only worked on
first event port associated with the evq.
