[SCSI] lpfc: NPIV: split ports

The driver is reorganized to separate the handling of the adapter from
the handling of the FC port. Adapter handling includes submissions of
command requests, receiving responses, and managing adapter resources.
The FC port includes the discovery engine, login handling, and the
mapping of a Scsi_Host on the "port".  Although not a large functional
change, as it touches core structures and functions, resulting in a
large text delta.
