    Change details:
    	- Add debugfs support to obtain firmware trace, saved firmware trace on
    	  an IOC crash, driver info and read/write to registers.
    
    	- debugfs hierarchy:
    	  bna/pci_dev:<pci_name>
    	  where the pci_name corresponds to the one under /sys/bus/pci/drivers/bna
    
    	- Following are the new debugfs entries added:
    	  fwtrc: collect current firmware trace.
    	  fwsave: collect last saved fw trace as a result of firmware crash.
    	  regwr: write one word to chip register
    	  regrd: read one or more words from chip register.
    	  drvinfo: collect the driver information.
