Jing Huang 293f82d59e [SCSI] bfa: enable new hardware
This patch enables support of new mezzanine cards for HP and IBM blade server.

- Add new pciids for HP and IBM mezzanine card.
- Add a new firmware image for HP mezzanine card, which is running in
  FC only mode. Rename firmware image to reflect the difference. Change the
  firmware download code accordingly for the above changes.
