pcihp: make PCI hotplug mmio handlers indifferent to PCI_HOTPLUG_ADDR
... removes dependency of mmio handler on PCI_HOTPLUG_ADDR. It will be needed in case of Q35 where base could be different. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
