scsi: lpfc: Add support for reporting encryption events

Support logging encryption events in both point-to-point and fabric
topologies.  A new LOG_ENCRYPTION flag is defined for reporting
encryption related events for HBAs that support the FEDIF feature.
Encryption information is stored in each NDLP object, which is
determined during the discovery stage after PLOGI completes.

For reporting encryption information to upper layers, the
.get_fc_rport_enc_info routine is implemented in lpfc_get_enc_info().
This allows encryption status to be reported through fc_remote_ports
sysfs.  Debugfs is also updated to report encryption information for all
NDLP objects.
