drm/amdgpu: implement the allocation range (v3)
Pass a ttm_placement pointer to amdgpu_bo_create_restricted add min_offset to amdgpu_bo_pin_restricted. This makes it easier to allocate memory with address restrictions. With this patch we can also enable 2-ended allocation again. v2: fix rebase conflicts v3: memset placements before using Reviewed-by: Jammy Zhou <Jammy.Zhou@amd.com> Signed-off-by: Chunming Zhou <david1.zhou@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
