bna: Add debugfs interface.
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.
