libata: implement ATA_FLAG_IGN_SIMPLEX and use it in sata_uli
Some uli controllers have stuck SIMPLEX bit which can't be cleared with ata_pci_clear_simplex(), but the controller is capable of doing DMAs on both channels simultaneously. Implement ATA_FLAG_IGN_SIMPLEX which makes libata ignore the simplex bit and use it in sata_uli. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
