ide: add proper PCI PM support (v2)
* Keep pointer to ->init_chipset method also in struct ide_host and set it in ide_host_alloc_all(). * Add ide_pci_suspend() and ide_pci_resume() helpers (default ->suspend and ->resume implementations). * ->init_chipset can no longer be marked __devinit. * Add proper PCI PM support to IDE PCI host drivers (rz1000.c and tc86c001.c are skipped for now since they need to be converted from using ->init_hwif to use ->init_chipset instead). v2: * Cleanup CONFIG_PM #ifdef-s per akpm's suggestion.
