scsi: lpfc: Add support for optional PLDV handling

Browse source

At adapter attachment or SLI port initialization, read the SLIPORT_STATUS
register to check for pldv_enable. If found, the driver will perform a PCIe
configuration space write when attaching to an SLI port instance that is an
LPe32000 series adapter.
