pci/pcihp: perform check for bus capability in pre_plug handler

Browse source 
Perform the check in the pre_plug handler. In addition, we need the
capability only if the device is actually hotplugged (and not created
during machine initialization). This is a preparation for coldplugging
pci devices via that hotplug handler.
