tests/acpi: unit test for 'acpi-pci-hotplug-with-bridge-support' bridge flag

Browse Source 
This change adds a new unit test for the global flag
'acpi-pci-hotplug-with-bridge-support' which is available for cold plugged pci
bridges in i440fx. The flag can be used to turn off ACPI based hotplug support
on all pci bridges.
