[SCSI] lpfc 8.2.4 : Make lpfc legacy I/O port free

Browse source 
This is a patch written by Tomohiro Kusumi and submitted to
linux-scsi:

http://marc.info/?l=linux-scsi&m=118673720712152&w=2

The original patch comment:

This patch makes Emulex lpfc driver legacy I/O port free.
It has already been acked quite long time ago.
So I resubmit the patch.
http://lkml.org/lkml/2006/11/22/28

Current lpfc driver is already using pci_select_bars()
and pci_enable_device_bars() when the PCI bus has been reset.
So I think this patch should also be acked.
