From: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
Change details:
- This patch is part of the BFA cleanup.
- Removing all BFA FCS handling related files, bfa_fcs.c, bfa_fcs_port.c,
bfa_fcs_uf.c & fabric.c.
- All the files will be merged into bfa_fcs.c in the subsequent patch.
- Removing first to make the review easier.
