[PATCH] acpiphp - slot management fix - V4

o This patch removes IDs (for slots management).
o This patch removes the slot register/unregister processes
  from the init/exit phases. Instead, adds these processes
  in the bridge add/cleanup phases.
o Currently, this change doesn't have any meanings. But
  these changes are needed to support p2p bridge(with
  hotplug slot)
