Cole Robinson 04c7d8b8de Fix pc migration from qemu <= 1.5
The following commit introduced a migration incompatibility:

commit 568f0690fd
Author: David Gibson <david@gibson.dropbear.id.au>
Date:   Thu Jun 6 18:48:49 2013 +1000

    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.
