ata fixes for 6.9-rc4

Browse source 
- Add the mask_port_map parameter to the ahci driver. This is a
    follow-up to the recent snafu with the ASMedia controller and its
    virtual port hidding port-multiplier devices. As ASMedia confirmed
    that there is no way to determine if these slow-to-probe virtual
    ports are actually representing the ports of a port-multiplier
    devices, this new parameter allow masking ports to significantly
    speed up probing during system boot, resulting in shorter boot times.
 
  - A fix for an incorrect handling of a port unlock in
    ata_scsi_dev_rescan().
 
  - Allow command duration limits to be detected for ACS-4 devices are
    there are such devices out in the field.
