Brennan Ashton 69ed5bb67d Various fixes for PCI work
Squashed commits:

1. Porting prior PCI work in place of jailhouse code

At this point the PCI enumeration works for x86_64 including over
pci-pci bridges.

Running QEMU with this configuration we see the bridge and the
device on the bridge.  It also detected the qemu test device

qemu-system-x86_64 \
  -cpu host,+pcid,+x2apic,+tsc-deadline,+xsave,+rdrand \
  --enable-kvm -smp 1 -m 2G -cdrom boot.iso --nographic -no-reboot \
  -device pci-testdev \
  -device pci-bridge,id=bridge0,chassis_nr=2 \
  -device e1000,bus=bridge0,addr=0x3
