From: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
Change details:
- This patch is part of the BFA cleanup.
- Removing all BFA FCPIM releated files, (ioim/fcpim/tskim/itnim)
- The files bfa_fcpim.c, bfa_ioim.c, bfa_tskim.c & bfa_itnim.c will be
unified into bfa_fcpim.c.
- Removing the files first to make the (diff reading) / review process easier.
