+  PciIoDevice   - A PCI_IO_DEVICE pointer to the PCI IO device to be registered.

-  For most of today's controllers, MaxDevices will either be 1 or 2. For SATA

-  is connected to a port multiplier, MaxDevices will be set to the number of SATA

-  support up to fifteen SATA devices, this number can be as large as fifteen. The IDE

-  Disqualifies specific modes for an IDE device.

-  This function allows the driver entity or other drivers (such as platform

-  to recalculate modes. This function allows the driver entity and the IDE 
-  controller driver to negotiate the timings on a per-device basis. This function 
-  is useful in the case of drives that lie about their capabilities. An example 
-  is when the IDE device fails to accept the timing modes that are calculated 
-  by the IDE controller driver based on the response to the Identify Drive command.
-
-  If the driver entity does not want to limit the ATA timing modes and leave that 
-  decision to the IDE controller driver, it can either not call this function for 
-  the given device or call this function and set the Valid flag to FALSE for all 
-  modes that are listed in EFI_ATA_COLLECTIVE_MODE.

-  specification for more information on PIO modes.  
-  
-  For Serial ATA (SATA) controllers, this member function can be used to disqualify

-    - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()

-
