* Made DPC an ACPI module dependency

Browse Source 
* Moved DPC queue creation / deletion before/after ACPI subsystem 
  init/shutdown repectively, as AcpiInitializeObjects() would 
  eventually trigger some AcpiOsExecute() call, which need DPC to be ready.
* Still missing:  a DPC queue that run each call in its own thread, not sequentially...
