hw/ppc/spapr: Adjust firmware name for PCI bridges 

SLOF uses "pci" as name for PCI bridges nodes in the device tree instead
of "pci-bridges", so booting via bootindex from a device behind a PCI
bridge currently does not work since QEMU passes the wrong name in the
"qemu,boot-list" property. Fix it by changing the name of the PCI bridge
nodes to "pci" instead.
