pci_client abstraction supports notification to application.
Each endpoint has to register with pci_client for notification which
return link_event_id after registration.
link_event_id is index in lookup table with total size as MAX_ENDPOINT.
This link_event_id is allocated sequential and does not match with ep_id
which is endpoint index with max as MAX_ENDPOINT.
stream-extension is not aware about link_event_id and uses ep_id for
notification which leads to mismatch in look up table finally dropping
notification.
Registering for link event in sequential manner does not help much as
registration against ep_id will make lookup table and endpoint database
one-to-one mapping.
Update endpoint registration for link event based on ep_id and use ep_id
in lookup table for notification purpose.
