atiixp/cs5535/scc_pata: fix "idex=ata66" parameter handling
Don't override the cable type if the "idex=ata66" parameter was used. While at it: * atiixp.c: factor out cable detection to atiixp_cable_detect() from init_hwif_atiixp(). * cs5535.c: pass 'ide_hwif_t *hwif' instead of 'struct pci_dev *dev' to cs5535_cable_detect(). * scc_pata.c: factor out cable detection to scc_cable_detect() from init_hwif_scc() and remove incorrect comment.
