scsi: lpfc: Add capability to register Platform Name ID to fabric

Browse source 
FC-LS and FC-GS specifications outline fields for registering a platform
name identifier (PNI) to the fabric.  The PNI assists fabrics with
identifying the physical server source of frames in the fabric.

lpfc generates a PNI based partially on the uuid specific for the
system.  Initial attempts to extract a uuid are made from SMBIOS's
System Information 08h uuid entry.  If SMBIOS DMI does not exist, a PNI
is not generated and PNI registration with the fabric is skipped.

The PNI is submitted in FLOGI and FDISC frames.  After successful fabric
login, the RSPNI_PNI CT frame is submitted to the fabric to register the
OS host name tying it to the PNI.
