x86/PCI: prevent re-allocation of already existing bridge and ROM
resources
PCI: acpiphp: kill SLOT_ENABLED in favor of always re-enumerating the

do the rescan anyway.
Because of that we must make sure that pcibios_resource_survey_bus() and
check_hotplug_bridge() get called only for a just found bus and not the
ones already added to the system. Failure to do so will lead to resource
conflicts.

Fix this by adding a DMI quirk for the Acer Aspire S5 machine that gives an
alternative path to the _RMV method.
