This change adds a unit test to exercise the case when hotplug is disabled
both for pci root bus and the pci bridges by passing the following two
switches to qemu:

  -global PIIX4_PM.acpi-root-pci-hotplug=off
  -global PIIX4_PM.acpi-pci-hotplug-with-bridge-support=off

bios-tables-test-allowed-diff.h documents the fact that a new DSDT acpi gold
master binary blob we need to be added to test this. We will do the actual
addition in the next patch in the series.
