drm/amdgpu: map wptr BO into GART
To support oversubscription, MES FW expects WPTR BOs to
be mapped into GART, before they are submitted to usermode
queues. This patch adds a function for the same.
V4: fix the wptr value before mapping lookup (Bas, Christian).
V5: Addressed review comments from Christian:
- Either pin object or allocate from GART, but not both.
- All the handling must be done with the VM locks held.
V7: Addressed review comments from Christian:
- Do not take vm->eviction_lock
- Use amdgpu_bo_gpu_offset to get the wptr_bo GPU offset
V8: Rebase
V9: Changed the function names from gfx_v11* to mes_v11*
V10: Remove unused adev (Harish)
