    ahci - Read DevSleep DETO and MDAT parameters using READ LOG EXT command.
    
    * DETO = DevSleep Exit Timeout in milliseconds
      MDAT = Minimum DEVSLP Assertion Time in milliseconds
    
    * In the next step, these parameters will be programmed in the DevSleep
      register, when automatic DevSleep power management is enabled, if
      available. If we failed to get these values, or if they were read as
      zero, we should fall back to the "nominal" values of 20ms for DETO and
      10ms for MDAT listed in the Serial ATA specification.
