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.)
