parentisci: unify isci_request and scic_sds_request (diff)

isci: unify isci_phy and scic_sds_phy
They are one in the same object so remove the distinction. The near duplicate fields (owning_port, and isci_port) will be cleaned up after the scic_sds_port isci_port unification. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
