MdeModulePkg Ata: Use the new (incompatible) PortMultiplierPort semantics

Browse Source 
The Mantis ticket 1353 <https://mantis.uefi.org/mantis/view.php?id=1353>
and Mantis ticket 1472 <https://mantis.uefi.org/mantis/view.php?id=1472>
updated the description of the port multiplier port number parameter in
SATA Device Path Node and ATA Pass-Through Protocol.

Now, this parameter should be set to 0xFFFF instead of 0 to indicate that
an ATA device is directly attached on the controller port.

Please note that this is an incompatible change. The consumer of SATA
device path or ATA_PASS_THRU needs to re-examine its usage to follow UEFI
2.5 mantis 1353 and 1472.
