Change details:
 - Replace IOC HB failure event notification with a more generic mechanism
   that is capable of sending enble, disable, and failed events to registered
   modules. As a result, cee  module event handling callback bfa_cee_hbfail()
   is replaced with bfa_cee_notify() so that it can receive and handle
   different events from IOC.

Fix the below compile warning:

drivers/net/bna/bfa_ioc.c:1922: warning: ‘bfa_ioc_smem_pgoff’ defined but not used

The variable 'pgoff' is set but unused in bfa_nw_ioc_fwver_get()
and bfa_ioc_download_fw().

Similarly for 'cmd_h' in bna_mbox_flush_q and the entirety of
bna_rit_mod_uninit() is unused since variables are purely set but no
action is made using them.

Same for 'bna' in bna_rit_create() and 'ret' in bna_rx_create().

Just kill them off.

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.

Change Details:
	- Added a check in ioc firmware lock function to see if IOC is
	in BFI_IOC_UNINIT state or not. If it is not in UNINIT state
	and the last IOC boot was not done by OS driver, force IOC state
	to BFI_IOC_UNINIT
	- Unused macro and API cleanup

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
