Some of PCI drivers require OS interfaces that can't be executed in the INIT context.
In that case we have to postpone PCI drivers probing and call it for example
in board initialization logic.

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
