drm/amdgpu: use doorbell mgr for kfd kernel doorbells
This patch:
- adds a doorbell bo in kfd device structure.
- creates doorbell page for kfd kernel usages.
- updates the get_kernel_doorbell and free_kernel_doorbell functions
accordingly
V2: Do not use wrapper API, use direct amdgpu_create_kernel(Alex)
V3:
- Move single variable declaration below (Christian)
- Add a to-do item to reuse the KGD kernel level doorbells for
KFD for non-MES cases, instead of reserving one page (Felix)
