[SCSI] bfa: Brocade-1860 Fabric Adapter Hardware Enablement

- Added support for Brocade-1860 Fabric Adapter.
- Made changes to support single firmware image per asic type.
- Combined bfi_cbreg.h and bfi_ctreg.h defines into bfi_reg.h with
  only minimal defines used by host.
- Added changes to setup CPE/RME Queue register offsets based on
  firmware response.
- Removed queue register offset initializations and added register offsets
  to BFI config response message.
- Added Brocade-1860 asic specific interrupt status definitions and
  mailbox interfaces.
