hw/pci-bridge: format special OFW unit address for PXB host
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern
/pci@i0cf8,%x/...
for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.
The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().
