[PATCH 14/40] tests: acpi: extend bridge tests with hotplugged bridges

[Igor Mammedov <imammedo@redhat.com>]

with previous commit fixing malformed PCNT calls to hotplugged
bridges, it should be possible add coldplug/hotplug test when
describing PCI topology in DSDT without breeaking CI.

Signed-off-by: Igor Mammedov <imammedo@redhat.com>

PS:
no need to update expected blobs as hotplugged bridges
shouldn't be visible (i.e. have its own slots described)
