Subject: [PATCH] [acpi driver model] Add device registration functions

- Create drivers/acpi/drivers/core/device.c
- Create (simple) acpi_device_register() and acpi_device_unregister()
- Add declarations to drivers/acpi/drivers/core/core.h
  (Not added to global include, since it should only be acpi core
  code that discovers devices).
