isci: unify isci_port and scic_sds_port
Remove the distinction between these two implementations and unify on isci_port (local instances named iport). The duplicate '->owning_port' and '->isci_port' in both isci_phy and isci_remote_device will be fixed in a later patch... this is just the straightforward rename/unification. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
