[SCSI] bfa: add debugfs support
- Add debugfs support to obtain firmware trace, driver trace
and read/write to registers.
- debugfs hierarchy:
/sys/kernel/debug/bfa/host#
where the host number corresponds to the one under /sys/class/scsi_host/host#
- Following are the new debugfs entries added:
drvtrc: collect current driver trace
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.
