ide: fix hwif_to_node()
hwif_to_node() incorrectly assumes that hwif->dev always belongs to a PCI device. This results in ide-cs oopsing in init_irq() after commit c56c5648a3bd15ff14c50f284b261140cd5b5472 accidentally fixed device tree registration for ide-cs. Fix it by using dev_to_node(). Thanks to Martin Michlmayr and Larry Finger for help with debugging the issue.
