[SCSI] lpfc 8.2.2 : Attribute and Parameter splits for vport and physical port

 - Split attributes up into vport and non-vport attributes.
 - Move vport specific cfg params to vport

Many of the vport-specific behaviors were still global attributes
on the physical port. Move them to the vport itself.
