The following commit introduced a migration incompatibility:
commit 568f0690fd9aa4d39d84b04c1a5dbb53a915c3fe

pci: Replace pci_find_domain() with more general pci_root_bus_path()
The issue is that i440fx savevm idstr went from 0000:00:00.0/I440FX to
0000:00.0/I440FX. Unfortunately we are stuck with the breakage for
1.6 machine types.
Add a compat property to maintain the busted idstr for the 1.6 machine
types, but revert to the old style format for 1.7+, and <= 1.5.
Tested with migration from qemu 1.5, qemu 1.6, and qemu.git.
