object_resolve_path should do to (a) figure whenever we are i440fx or
q35 and (b) get the pcihost device (then read enable_s3 etc properties).

For pvpanic (and maybe others) it might be handy to have "find me the
device of type TYPE_ISA_PVPANIC_DEVICE, anywhere in the tree"
functionality, so the same code works no matter where the isa bridge
happens to live.  Or "find me all pci bridges in the system".

Is object_foreach_child recursive?  Then it might do the job ...
