			When passing through an USB storage device to a pseries guest, it is currently not possible to automatically boot from the device if the "bootindex" property has been specified, too (e.g. when using "-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0" at the command line). The problem is that QEMU builds a device tree path like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF in the /chosen/qemu,boot-list property. SLOF, however, probes the USB device, recognizes that it is a storage device and thus changes its name to "storage", and additionally adds a child node for the SCSI LUN, so the correct boot path in SLOF is something like "/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead. So when we detect an USB mass storage device with SCSI interface, we've got to adjust the firmware boot-device path properly that SLOF can automatically boot from the device.
