currently libata-sff is completely ignoring the enabled/disabled status of the interfaces. This is a real problem on parisc because if you touch a non responding memory area (i.e. a disabled interface) you crash the box. Fix this up by restoring the enablebits logic to the pata_cmd64x driver. To do this, libata-sff has to be modified not to probe both ports if we don't have them. This is done by reintroducing IDE_HFLAG_SINGLE flag as ATA_HOST_SFF_SINGLE_PORT which drivers can use to condition libata-sff port probing.
