During a kernel crash, bna control path state machine and firmware do not
get a notification and hence are not cleanly shutdown. The registers
holding driver/IOC state information are not reset back to valid
disabled/parking values. This causes subsequent driver initialization
to hang during kdump kernel boot. This patch, during the initialization
of first PCI function, resets corresponding register when unclean shutown
is detect by reading chip registers. This will make sure that ioc/fw
gets clean re-initialization.

Change Details:
	- Made IOC auto_recovery synchronized and not timer based.
	- Only one PCI function will attempt to recover and reinitialize
	the ASIC on a failure, that too after all the active PCI
	functions acknowledge the IOC failure.

As suggested by Stephen Hemminger:
1) Made functions and data structures static wherever possible.
2) Removed unused code.

This is the patch to fix the build break caused by multiple
definitions of symbols between Brocade's FC/FCOE driver(BFA)
and 10G Networking Driver(BNA).

Changes are:

1. locally used functions are made static 

2. unused functions are removed

3. using unique namespaces for the function names that must be
globally visible

Clear PSS memory reset that is set as part of power-on-reset (pci reset).
Complete PMM memory reset before BISTR start. Clear EDRAM BISTR start bit
after fixed delay. BISTR DONE bit status is not getting set. Use a fixed
1ms delay for BISTR now. Expose PMM IT memory definitions to host.

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.

Add support for faster IOC recovery after failure.

Split bfa_ioc.c into three files:
  bfa_ioc.c:    Common code shared between crossbow and catapult ASIC's.

  bfa_ioc_cb.c: Code specific to the crossbow, reg mapping and
                interrupt related routines.

  bfa_ioc_ct.c: Code specific to the catapult, reg mapping and
                interrupt related routines.

Fix to make sure IOC reinitialize's properly on enable request -
update the ioc_fwstate reg with BFI_IOC_FAIL on ioc disable mbox cmd
timeout.

Makefile changes to support the 2 newly added files bfa_ioc_cb.c and
bfa_ioc_ct.c.
