[Qemu-devel] [PATCH for-1.6] pc: disable pci-info for 1.6

[Michael S. Tsirkin]

The BIOS that we ship in 1.6 does not use pci info
from host (yet). So it's safest to disable that
interface for 1.6 machine types for now, leave it on for 1.7
as we have enough time to fix issues if any.

Surely the numbers aren't right here.  Aren't you now enabling
pci_info for 1.5, when it was disabled previously?
