[SCSI] bfa: Store port configuration in flash for persistency.
When the bfa driver is loaded a flogi is sent without the knowledge of
trunking configuration. This normal flogi causes the switch ports
which had trunking enabled to go to persistent offline. Solution is
to store the port configuration (which has trunking info) in the flash
for persistency. The firmware will read this configuration when the
very first fcport enable is received.
