OvmfPkg: QemuBootOrderLib: recognize Q35 SATA disks / CD-ROMs

The OpenFirmware device paths that QEMU generates for these disks and
CD-ROMs are very similar to those generated for the i440fx IDE disks and
CD-ROMs (including the same number of devpath nodes necessary for unique
parsing). The interpretations and the translation to UEFI devpath
fragments are different, of course.

(The spaces after "ide@1,1" are inserted below only for illustration
purposes.)

                                                 primary or secondary
                                                 |      master or slave
                                                 v      v
  i440fx IDE: /pci@i0cf8/ide@1,1          /drive@0/disk@0
  Q35 SATA:   /pci@i0cf8/pci8086,2922@1f,2/drive@1/disk@0
                                                 ^      ^
                                                 |      device number
                                                 |      (fixed 0)
                                                 channel (port) number

The similarity is reflected in the translation output (spaces again
inserted for illustration only):

  i440fx IDE: PciRoot(0x0)/Pci(0x1,0x1) /Ata(Primary,Master,0x0)
  Q35 SATA:   PciRoot(0x0)/Pci(0x1F,0x2)/Sata(0x1,0x0,0x0)
                                              ^   ^   ^
                                              |   |   LUN;
                                              |   |   always 0 on Q35
                                              |   port multiplier port
                                              |   number; always 0 on Q35
                                              channel (port) number
