Dmitry Kravkov 523224a3b3 bnx2x, cnic, bnx2i: use new FW/HSI 
This is the new FW HSI blob and the relevant definitions without logic changes.
It also included code adaptation for new HSI. New features are not enabled.

New FW/HSI includes:
- Support for 57712 HW
- Future support for VF (not used)
- Improvements in FW interrupts scheme
- FW FCoE hooks (stubs for future usage)
