OvmfPkg/QemuBootOrderLib: adapt Q35 SATA PMPN to UEFI spec Mantis 1353
On the Q35 machine type of QEMU, there is no port multiplier connected to the on-board SATA controller. Therefore the AtaAtapiPassThru driver update for Mantis ticket 1353 <https://mantis.uefi.org/mantis/view.php?id=1353> changes the middle number (the Port Multiplier Port Number) in the Sata() device path nodes from 0x0 to 0xFFFF. Adapt the translation from OpenFirmware in QemuBootOrderLib. (Note: QemuBootOrderLib is deprecated at this point (see USE_OLD_BDS in the DSC files), but until we remove it, it should be kept in sync with QemuNewBootOrderLib.)
