Root cause: When kernel crashes, bfa IOC state machine and FW doesn't get
a notification and hence are not cleanly shutdown. So 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.

Fix description: during the initialization of first PCI function, reset
corresponding register when unclean shutown is detect by reading chip
registers. This will make sure that ioc/fw gets clean re-initialization.
