qemu uses "pci" as name for pci bridges in the firmware device path.
seabios expects "pci-bridge". Result is that bootorder is broken for
devices behind pci bridges.
Some googling suggests that "pci-bridge" is the correct one. At least
PPC-based Apple machines are using this. See question "How do I boot
from a device attached to a PCI card" here:
http://www.netbsd.org/ports/macppc/faq.html
So lets change qemu to use "pci-bridge" too.
