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.
