    ahci - Properly check and set SATA capabilities and features for ALPM.
    
    - This should now only enable device-initiated and/or host-initiated link
      power-management when it is supported by both controller and disk device.
    
    - Also this now allows for device-initiated power-management to be enabled
      with AHCI controllers that don't support automatic host-initiated
      power-management.
    
    - In addition, this adds support for automatic promotion of "partial" state
      to "slumber" state (i.e. without needing to go through "active" state).
    
    - The kernel console output now explicitly tells when it's enabling DIPM
      (device-initiated power management) and HIPM (host-initiated power
      management) respectively.
