Tejun Heo b2a8bbe67d 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.
