ide: remove ide_find_best_pio_mode()
* Add ->host_flags to ide_hwif_t to store ide_pci_device_t.host_flags, assign it in setup-pci.c:ide_pci_setup_ports(). * Add IDE_HFLAG_PIO_NO_{BLACKLIST,DOWNGRADE} to ide_pci_device_t.host_flags and teach ide_get_best_pio_mode() about them. Also remove needless !drive->id check while at it (drive->id is always present). * Convert amd74xx, via82cxxx and ide-timing.h to use ide_get_best_pio_mode() and then remove no longer needed ide_find_best_pio_mode(). There should be no functionality changes caused by this patch. Acked-by: Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
