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 QemuNewBootOrderLib.
