ide: separate PCI specific init from generic init in ide_pci_setup_ports()
* Setup ->mate and ->channel in ide_pci_setup_ports() instead of
in ide_hwif_configure().
* Make 'port' parameter for ide_hwif_configure() 'unsigned int'.
* Separate PCI specific init from generic init in ide_pci_setup_ports().
