via82cxxx: fix SATA cable detection
Add VIA_SATA_PATA flag for cx700, vx800 and vx855 chipsets (the first port is SATA). Based on commits 7585eb1, bfce5e0 and e4d866c for pata_via host driver. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
