Building amdkfd without MMU notifiers is broken:

In file included from drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager_vi.c:28:
drivers/gpu/drm/amd/amdkfd/kfd_priv.h:584:22: error: field 'mmu_notifier' has incomplete type

This adds the missing 'select MMU_NOTIFIER' line to make it build
cleanly all the time.

Acked-by: Christian König <christian.koenig@xxxxxxx>, but I would wait on what Felix says to that.
