Upcall: Process each of the upcall events separately
As suggested during the code-review of Bug1200262, have modified GF_CBK_UPCALL to be exlusively GF_CBK_CACHE_INVALIDATION. Thus, for any new upcall event, a new CBK procedure will be added. Also made changes to store upcall data separately based on the upcall event type received.
