[PATCHv2 4/8] ata: sata_dwc_460ex: drop redundant struct copy of port_info

[Rosen Penev <rosenp@gmail.com>]

sata_dwc_port_info[0] was copied to a local auto variable before being
referenced via a pointer array.  The local copy is never modified, so
drop it and point ppi directly at the static data.  This saves ~104
bytes of stack and makes the const qualification consistent.
