drm/amdkfd: Encapsulate DQM functions in ops structure
This patch does some re-org on the device_queue_manager structure. It takes out
all the function pointers from the structure and puts them in a new structure,
called device_queue_manager_ops. Then, it puts an instance of that structure
inside device_queue_manager.
This re-org is done to prepare the DQM module to support more than one AMD APU
(Kaveri).
